Vedclass · Answer

(B) The work done in moving a charge $q$ from one point to another is given by $W = q(V_{final} - V_{initial})$.Since there is no charge nearby, the electric potential $V$ is constant throughout the region (or zero if we consider infinity as reference).Points $A, B,$ and $C$ lie on a curve, but without any external electric field or source charge, the potential at all points in the space is the same.Therefore, the potential difference between point $P$ and any point $A, B,$ or $C$ is zero.Thus, $W_A = q(V_A - V_P) = 0$, $W_B = q(V_B - V_P) = 0$, and $W_C = q(V_C - V_P) = 0$.Hence, $W_A = W_B = W_C = 0$.

In the following diagram, the work done in moving a point charge from point $P$ to points $A, B$ and $C$ is $W_A, W_B$ and $W_C$ respectively. If there is no charge nearby, then:
