Question

In the given figure change $+Q$ is placed at the centre of a dotted circle . Work done in taking another charge $+q$ from $A$ to $B$ is $W_1$ and from B to C is $W_2$ Which one of the following is correct $W_1>W_2,W_1=W_2$ and $W_1<W_2$?

Answer 1

A, C and B are at same distance from the $center.$ So the potential at all these 3 points will be same not work done, $W_1$, $W_2$

should be $zero$ because the potential difference is zero.

So $W_1=W_2$
