A charged particle of mass m₁ and charge q₁ is revolving in a circle of radius r. Another charged particle of charge q₂ and mass m₂ 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

$$v = \sqrt {{{{q_1}{q_2}r} \over {4\pi {\varepsilon _0}{m_1}}}} $$

B

$$v = {1 \over {{m_1}}}\sqrt {{{{q_1}{q_2}} \over {4\pi {\varepsilon _0}r}}} $$

C

$$T = \sqrt {{{16{\pi ^3}{\varepsilon _0}m_1^2{r^3}} \over {{q_1}{q_2}}}} $$

D

$$T = \sqrt {{{16{\pi ^3}{\varepsilon _0}m_1^{}{r^3}} \over {{q_1}{q_2}}}} $$
