Question

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. $W_{A} < W_{B} < W_{C}$

Answer 1

Answer: (B)

Charge when moved in a space of no field, does not experience any force and no work is done.
$W_{A}=W_{B} =W_{C}=0$
