Two particles are moving in a uniform magnetic field in circular orbits such that m1 / m2 = 9/4 and r1/r2 = 6/5.

Question

Two particles are moving in a uniform magnetic field in circular orbits such that \(\frac{m_1}{m_2} = \frac94\) and \(\frac{r_1}{r_2} = \frac65\). If two particles have same K.E. Then find the ratio of their charges

(1) \(\frac34\)

(2) \(\frac14\)

(3) \(\frac24\)

(4) \(\frac54\)

Answer 1

Correct option is (4) \(\frac54\)
