In which direction does the electric field point at position directly east of a positive charge?
Yes. The electric field in physics is represented by a vector, it has three components governing the field strength in the up-down, left-right and forward-backwards directions.
What are field lines?
Field lines are visual representations used in physics to illustrate the direction of force acting on an object within a field, such as an electric or magnetic field. Field lines show the pathways that a small positive test charge would follow if placed in the field. The density of field lines indicates the strength of the field at different points.
If you place a charge into an electric fieldit will move in the direction indicated by the electric field lines?
Yes, a charge placed in an electric field will experience a force in the direction of the field lines due to the interaction between the charge and the field. The charge will move along the field lines if it is free to do so.
What is the relationship between the electric field (E), permittivity of free space (), and electric charge density () in a given system?
The relationship between the electric field (E), permittivity of free space (), and electric charge density () in a given system is described by Gauss's Law, which states that the electric field (E) at a point in space is directly proportional to the electric charge density () at that point and inversely proportional to the permittivity of free space (). Mathematically, this relationship is represented as E / .
What is the relationship between the electric field intensity (E), charge density (q), and permittivity of free space ()?
The relationship between the electric field intensity (E), charge density (q), and permittivity of free space () is given by the equation E q / (). This equation shows that the electric field intensity is directly proportional to the charge density and inversely proportional to the permittivity of free space.

What are the electric field equations for different geometries?
The electric field equations for different geometries are: For a point charge: E kq/r2, where E is the electric field, k is the Coulomb's constant, q is the charge, and r is the distance from the charge. For a uniformly charged infinite line: E 2k/r, where E is the electric field, k is the Coulomb's constant, is the charge density, and r is the distance from the line. For a uniformly charged infinite plane: E /2, where E is the electric field, is the surface charge density, and is the permittivity of free space.
What is the formula for calculating the electric field of a cylinder?
The formula for calculating the electric field of a cylinder is E / (2r), where E is the electric field, is the charge density of the cylinder, is the permittivity of free space, and r is the distance from the axis of the cylinder.
What is the electric field of a cylinder shell?
The electric field of a cylinder shell is the force per unit charge experienced by a charge placed at a point outside the cylinder shell. It is calculated using the formula E / (2r), where E is the electric field, is the charge density of the cylinder shell, is the permittivity of free space, and r is the distance from the axis of the cylinder shell to the point where the electric field is being measured.
How electric current flow in metal?
Electric current flows in metals due to the movement of free electrons. When a voltage is applied across a metal conductor, the electric field created causes the free electrons to move in the direction of the field, creating a flow of charge which we refer to as electric current.
What does a collection of free electrons in one place create?
A collection of free electrons in one place creates an electric charge. These free electrons can move under the influence of an electric field, leading to the flow of electric current.
If a conductor is placed in a uniform electric field does the conductor gain any charge?
The conductor will not gain any charge that is not placed on it by you. However, the electric field will displace the free charges already within the conductor (by its nature) such that there will be a non-uniform surface charge density. Remember: a conductor must have zero electric field inside it, so the charges rearrange to cancel the external E-field. Again, this only repositions the existing charge, but it does not add or remove any charge.
What causes charge to flow in a conducting wire?
The flow of charge in a conducting wire is caused by the presence of an electric field. When a potential difference (voltage) is applied across the wire, it creates an electric field that exerts a force on the free electrons in the wire, causing them to move and create an electric current.
