The surface charge density of an infinite charged sheet is `10^-7 Cm^-2`If the potential difference between two equipotential surfaces be 5 V, then what is the distance between the surfaces?

What is surface charge density?

Can two different equipotential surfaces intersect each other?

Angle between an equipotential surface and electric lines of force is

Angle between an equipotential surface and electric lines of force is

The unit of surface density of charge in SI is

Define surface density of electric charge

The earth's surface has a negative surface charge density of 10^-9C.m^-2 . The potential difference of 400kV between the top of the atmosphere and the surface results (due to the low conductivity of the lower atmosphere) in a current of only 1800 A over the entire globe. If there wre no mechanism of sustaining atmospheric,electric field, how much time (roughly) would be required to neutralise earth's surface? [Radius of earth = 6.37 times 10^6m ]

What is meant by surface density of charge ?

What is the work done in moving a charge of 10nC between two points on a equipotential surface?

What are the shapes of the equipotential surfaces in the field of a point charge?
