A charged ring has mass mand radius R. A point charge qand mass M is placed at its centre. If total potential energy of the system is zero, then find charge on the ring.

Option: 1

\frac{4 \pi t_0 G m}{q} \cdot M


Option: 2

\frac{2 \pi \epsilon_0 G m}{q} \cdot M


Option: 3

\frac{\pi \epsilon_0 G m}{2} \cdot m


Option: 4

\frac{4 \pi \epsilon_0 \mathrm{Gm}}{3 q} \cdot M

If Q is the charge of the ring, then


\mathrm{\begin{aligned} & \left(\frac{1}{4 \pi \epsilon_0}\right) \frac{Q q}{R}-\frac{G M}{R} m=0 \\ & \frac{1}{4 \pi \epsilon_0} \frac{Q q}{R}=\frac{G M}{R} \cdot m \\ & Q=\frac{4 \pi \epsilon_0 G M}{q} \cdot m \end{aligned} }
