A proton and an -particle enter a uniform magnetic field perpendicularly with the same speed. If proton takes 25 ~s to make 5 revolutions, then the periodic time for the -particle would be

Options

  1. A50 ~s
  2. B25 ~s
  3. C10 ~s
  4. D5 ~s

Correct answer

C. 10 ~s

Step-by-step solution

Time period of proton T_p= 25 5 =5 ~s By using T= 2 m q B aligned & T_ T_p = m_ m_p q_p q_ = 4 m_p m_p q_p 2 q_p =2 & T_ =2 T_p=10 ~s aligned
