Vedclass · Answer

(C) The electric potential $V$ at a distance $r$ from a point charge $+q$ is given by $V = \frac{kq}{r}$.Since points $A, B, C, D$ and $E$ are all at the same distance $r$ from the point charge $+q$, they all lie on the same equipotential surface.The work done in moving a charge $q_0$ between any two points on an equipotential surface is given by $W = q_0(V_{final} - V_{initial})$.Since $V_{final} = V_{initial}$ for any two points on this surface, the work done $W = 0$.Therefore, the work done is zero along all the paths $AB, AC, AD$ and $AE$.

In the electric field of a point charge $+q$, a certain charge is carried from point $A$ to points $B, C, D$ and $E$ along the paths shown in the figure. Then the work done:
