Where is the electric field around a charged obhect most intense?
The electric field around a charged object is most intense near the surface of the object where the charge is located. As you move away from the charged object, the electric field strength decreases.
Why electric field lines are always perpendicular to the surface of the conductor?
Electric field lines are always perpendicular to the surface of a conductor because in electrostatic equilibrium, the electric field inside a conductor is zero. Any component of the electric field parallel to the surface would result in the flow of charges until the electric field is perpendicular to the surface, ensuring a state of equilibrium.
Will an electric charge spread over and entire balloon?
Yes, an electric charge can spread over the entire surface of a balloon. When a balloon is charged, the charge will distribute itself evenly across the surface due to electrostatic forces.
What is the magnitude of the electric field inside the dome of a highly-charged Van de Graaff generator?
The magnitude of the electric field inside the dome of a highly-charged Van de Graaff generator is very high due to the accumulation of electric charge on the surface of the dome. This strong electric field is responsible for creating the potential difference that allows the generator to produce static electricity.
What happens when an isolated conductor is statically charged?
When a conductor is statically charged, excess charge accumulates on its surface. This charge distribution creates an electric field within the conductor that repels like charges and attracts opposite charges. As a result, the charges redistribute themselves on the surface of the conductor until the electric field inside the conductor becomes zero.
Does your body have electric charge?
yes your body is both negatively charged and positively charged on the extracellular surface
Where is the electric field around a charged obhect most intense?
The electric field around a charged object is most intense near the surface of the object where the charge is located. As you move away from the charged object, the electric field strength decreases.
What is maximum and minimum electric flux?
As we know that electric flux is the total number of electric lines of forces passing through a surface. Maximum Flux: Electric flux through a surface will be maximum when electric lines of forces are perpendicular to the surface. Minimum flux: Electric flux through a surface will be minimum or zero when electric lines of forces are parallel to the surface.
What is direction of the electric fields field near the earth's surface?
The electric field near the Earth's surface typically points vertically downward, towards the Earth. This is because the Earth's surface is negatively charged and repels negative charges, causing the electric field to point towards the surface.
Why electric field lines are always perpendicular to the surface of the conductor?
Electric field lines are always perpendicular to the surface of a conductor because in electrostatic equilibrium, the electric field inside a conductor is zero. Any component of the electric field parallel to the surface would result in the flow of charges until the electric field is perpendicular to the surface, ensuring a state of equilibrium.
Why must electric field line be perpendicular to equipotential surfaces?
If the field lines were not perpendicular to the surface, then they could be decomposed into components perpendicular and parallel to the surface. But if there is an E-field along the surface, the surface is no longer an equipotential.
Will an electric charge spread over and entire balloon?
Yes, an electric charge can spread over the entire surface of a balloon. When a balloon is charged, the charge will distribute itself evenly across the surface due to electrostatic forces.
What quality must the charge density on the surface of a conducting wire possess if an electric field is to act on the negatively charged electrons inside the wire?
The charge density on the surface of a conducting wire must be nonuniform, with a tangential component to the surface, in order for an electric field to act on the negatively charged electrons inside the wire. This nonuniform charge distribution creates an electric field inside the wire, allowing for the movement of the electrons.
How is a stactically charged ion formed?
A statically charged ion is formed when there is an imbalance of electric charges within or on the surface of a material especially relatively non-conductive insulators such as plastics, paper, glass, and ceramics.
What is the magnitude of the electric field inside the dome of a highly-charged Van de Graaff generator?
The magnitude of the electric field inside the dome of a highly-charged Van de Graaff generator is very high due to the accumulation of electric charge on the surface of the dome. This strong electric field is responsible for creating the potential difference that allows the generator to produce static electricity.
What would happen if a charged particle strikes the earth's magnetic field at the equator?
It would be induced to follow the lines of force in a clockwise spiral. As the lines of force at the equator are parallel to the surface of the Earth, the charged particle would be deflected northwards.
Why are the equipotential lines near conductor surfaces parallel to the surface?
For conductors, the electric field perpendicular to its surface and no field exist within the conductor. As a result the equipotential lines are found near the surface. They are parallel to the surface since equipotential are perpendicular to field lines.
