Two charges +q and -q are placed at points A and B respectively which are at a distance 2 L_{\text{ppat }} C is the mid point of A and B. The work done in moving a charge +Q along the semicircle {\CSD} (W_V) and along the line {\CBD} (W_2) are

Correct Answer is : qQ4πE0L,qQ4πE0L

\frac{q Q}{4 \pi E_0 L}, \frac{q Q}{4 \pi E_0 L}

\frac{-Q q}{6 \pi E_0 L}, \frac{-Q q}{6 \pi E_0 L}

\frac{-Q q}{6 \pi E_0 L}, \frac{-Q q}{12 \pi E_0 L}
