Q.
In the following diagram the work done in moving a point charge from point $P$ to point $A,B$ and $C$ is respectively as $W_{A},W_{B}$ and $W_{C},$ then
A) $W_{A} = W_{B} = W_{C}$
B) $W_{A} = W_{B} = W_{C} = 0$
C) $W_{A} > W_{B} > W_{C}$
D) $W_{A} < W_{B} < W_{C}$
Explanation
(b) According to the figure, there is no other charge. A single charge when moved in a space of no field, does not experience any force. No work is done
$W_{A} = W_{B} = W_{C} = 0$
