Question

In the electric field of a point charge q , a certain charge is carried from point A to $\mathrm{B}, \mathrm{C}, \mathrm{D}$ and E . Then the work done

Professor PC Thomas Classes · Answer

$\mathrm{W}_{\mathrm{AB}}=\left(\mathrm{V}_{\mathrm{B}}-\mathrm{V}_{\mathrm{A}}ight) \mathrm{q}=0$ since $\mathrm{V}_{\mathrm{A}}=\mathrm{V}_{\mathrm{B}}$ Similarly $\mathrm{W}_{\mathrm{AC}}=\left(\mathrm{V}_{\mathrm{C}}-\mathrm{V}_{\mathrm{A}}ight) \mathrm{q}=0$ $$ \begin{aligned} & W_{A D}=\left(V_{D}-V_{A}ight) q=0 \ 	herefore & W_{A B}=W_{A C}=W_{A D}=0 \end{aligned} $$
