A charged particle of mass \(m_{1}\) and charge \(q_{1}\) is revolving in a circle of radius \(r .\) Another charged particle of charge \(q_{2}\) and mass \(m_{2}\) is situated at the centre of the circle. If the velocity and time period of the revolving particle be \(v\) and \(T\) respectively, then
- A \(v=\sqrt{\frac{q \cdot q_{2} r}{4 \pi \varepsilon_{0} m_{1}}}\)
- B \(v=\frac{1}{m_{1}} \sqrt{\frac{q_{1} q_{2}}{4 \pi \varepsilon_{0} r}}\)
- C \(T=\sqrt{\frac{16 \pi^{3} \varepsilon_{0} m_{1}^{2} r^{3}}{q_{1} q_{2}}}\)
