Q.
In the electric field of a point charge $q,$ a certain point charges is carried from point A to B, C, D and E as shown in figure. The work done is
A) Least along the path AE
B) Least along the path AC
C) Zero along any one of the paths
D) Least along AB
Explanation
(c) For charge $q\ $placed at the centre of circle, the circular path is an equipotential surface and hence works done along all paths $AB$ or AC or AD or AE is zero.
