2. Electric Potential and Capacitance
easy
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
$W_A < W_B < W_C$
Solution
(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.
${W_A} = {W_B} = {W_C} = 0$
