easy

In the electric field of a 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 paths $AB,\;AC,\;AD$ and $AE$

D

Is least along $AE$

Solution

(c) $ABCDE$ is an equipotential surface, on equipotential surface no work is done in shifting a charge from one place to another.
