Question

Define equipotential surface and its properties no short full define?

Answer 1

Answer:

Any surface over which the electric potential is same everywhere is called an equipotential surface.

The properties of equipotential surface are:

• No work is done in moving a charge between any two points on an equipotential surface. This is so because the potential difference between any two points on the surface is zero.

• The electric field, and hence lies of force, are everywhere at right angles to the equipotential surface. This is so because there is no potential gradient along any direction parallel to the surface and no electric field parallel to the surface.

Answer 2

An equipotential surface is the surface which has same potential at its every point. (i) (ii) The electric field due to single charge is not constant, this is the reason why the equipotential surfaces about a single charge are not equidiatant.
