Q.
In the electric field of point charge $q,$ a certain charge is carried from point $A$ to $B,C,D$ and $E$. Then the work done
A) Is least along the path $AB$
B) Is least along the path $AD$
C) Is zero along all the parts $AB,\ AC,AD$ and $AE$
D) Is least along $AE$
Explanation
(c) ABCDE is an equipotential surface, on equipotential surface no work is done in shifting a charge from one place to another
