What is meant by electric field intencity?
An electric field can be represented diagrammatically as a set of lines with arrows on, called electric field-lines, which fill space. Electric field-lines are drawn according to the following rules: The direction of the electric field is everywhere tangent to the field-lines, in the sense of the arrows on the lines. The magnitude of the field is proportional to the number of field-lines per unit area passing through a small surface normal to the lines. Thus, field-lines determine the magnitude, as well as the direction, of the electric field. In particular, the field is strong at points where the field-lines are closely spaced, and weak at points where they are far apart. Electric Field intensity It was stated that the electric field concept arose in an effort to explain action-at-a-distance forces. All charged objects create an electric field which extends outward into the space which surrounds it. The charge alters that space, causing any other charged object that enters the space to be affected by this field. The strength of the electric field is dependent upon how charged the object creating the field is and upon the distance of separation from the charged object. In this section of Lesson 4, we will investigate electric field from a numerical viewpoint - the electric field strength.

How many correctly placed plates are there in the set?
There are six correctly placed plates in the set.
What is the force between two charge particle when medium is placed between them?
The force between two charged particles in a medium will depend on the properties of the medium, such as its dielectric constant. The force will be reduced compared to if the particles were in a vacuum, due to the screening effect of the medium on the electric field between the charges. The force will be weaker as the dielectric constant of the medium increases.
What is the relationship between the direction of an electric field and the direction of the force that the field would exert?
The direction of an electric field is the direction of the force that the field would exert on a proton.. ___ The relationship of the direction of an electric field and the direction of force that the field would exert are the same. Let's look. Consider the humble electron, the carrier of the negative electrostatic force. The electric field around the electron can be said to "stand out around the electron" equally and in all directions. We need to form a mental picture, so let's try to do that. Think of the electron as a little ball floating in space. Now picture it with long, thin "needles" sticking out of it in all directions. Each needle is a line of electric force, and its direction is "out" or "away" from the center of the ball that is the electron. Got that picture? The negative electric force about any elementary charged particle is just like the picture we have of the electron and its electric field. The force acts "out" like that. In the case of a positively charged particle, the same model applies, except that positive and negative forces attract while two negative or two positive forces repel each other, just as is set down in the law of electrostatics. Simple and easy. Note that electric and magnetic fields have a little different way of interacting, and this question doesn't cover that.
How can you test for helium?
One common way to test for helium is to use a helium leak detector, which can detect very small amounts of helium gas. Helium can also be identified using a mass spectrometer, since it has a unique mass-to-charge ratio. Additionally, helium can be detected by its characteristic orange glow when placed in an electric field.
An electric dipole placed with its axis inclined at an angle to the direction of a uniform electric field experiences?
It experiences a torque but no force. As the dipole is placed at an angle to the direction of a uniform electric field it experiences two opposite and equal forces which are not along the same line. This develops a torque which aligns the dipole along the field. The dipole does not experience any force as the two forces cancel each other.
What happens when the electric field is applied to a very polar molecule?
dipole when placed in nonuniform electric field it experiences a net force if field is varying in direction but if field is nonuniform in magnitude then force depends on its posititon it may experience a torque again depends on depends on its posititon so it may translate as well as rotate
How electric field is equal to force by dipole moment?
The electric field produced by a dipole at a distance is given by the formula E = 2kP/r^3, where k is the electrostatic constant, P is the dipole moment, and r is the distance from the dipole. This electric field exerts a force on a test charge q placed in the field, given by F = qE. Therefore, the force on a charge due to a dipole moment is directly proportional to the dipole moment and the charge, according to these equations.
Electric dipole in uniform magnetic field?
An electric dipole consists of two equal and opposite charges separated by a distance. When placed in a uniform magnetic field, the charges experience a force in opposite directions due to their opposite velocities in the field. This results in a torque acting to align the dipole along the field lines of the magnetic field.
Why dipole have a direction from negative charge to positive charge?
In a dipole, the direction is defined from negative to positive because it aligns with the convention of electric field direction, which is considered to go from positive to negative charges. This convention allows for consistency in analyzing and understanding the behavior of electric fields and dipoles in various systems and contexts.
What would be the acceleration of a positive test charge placed at this midpoint?
-- It depends on the value of the positive test-charge, and on the quantity, sign, and physical distribution of the charges situated around that midpoint. -- It also depends on the mass of the object carrying the positive test-charge. Sadly, none of this information is included in the question.
Why an insulator is also called dielectric?
An insulator is also called a dielectric because it is a material that does not conduct electricity easily due to its high resistance to the flow of electric current. Dielectrics are used in capacitors to store and release electrical energy. When placed in an electric field, dielectrics become polarized, creating an electric dipole moment that affects the overall behavior of the material in the field.
If a magnetic dipole is placed in a magnetic field the dipole is found to have both rotational and translational motion.what would you infer about the magnetic field?
If a magnetic dipole placed in a magnetic field exhibits both rotational and translational motion, it suggests that the magnetic field is not uniform. A non-uniform magnetic field will exert torque on the magnetic dipole, causing it to rotate, and may also impart a force causing translational motion. These observations can help characterize the spatial variation of the magnetic field.
What will happen to the electric field when a dielectric is placed?
The electric field is weakened when a dielectric is inserted.
What is the potential energy of a point magnetic dipole of moment M placed in a uniform magnetic field B?
The potential energy of a magnetic dipole in a magnetic field is given by U = -M · B, where M is the magnetic moment and B is the magnetic field. The negative sign indicates that the potential energy decreases as the dipole aligns with the field.
What are Dipole-dipole properties?
any atom or molecule or any group placed in electric field ,induced and two pole generate..in liquid form when we take it as solvent then it exerts the force on solute molecule,if contains that configuration by which it could rearrange and feel a force by solvent molecule means its generated pole attract oppositely to solvent molecule this way always increase its solubility...we can calculate this force also..if it is a solid matter then we can see more properties of its path in magnetic or electric field,can work as capaciter ...
Is cf2 polar?
Yes, CF2 is a nonpolar molecule because it has a linear geometry with symmetrically placed fluorine atoms, resulting in a net dipole moment of zero.
