Figure shows the electric lines of force emerging from a charged body. If the electric field at A and B are and
respectively and if the displacement between A and B is r then

As we learned,
Field line do not exist inside a conductor -
E = 0
-
In non-uniform electric field. Intensity is more, where the lines are more denser.
