A particle of mass m , charge Q and kinetic energy T enters a transverse uniform magnetic field of induction B . After 3 seconds the kinetic energy of the particle will be

Options

  1. A4 ~T
  2. B3 ~T
  3. C2 ~T
  4. DT

Correct answer

D. T

Step-by-step solution

Work done by magnetic field on charge particle is zero. Therefore its kinetic energy will be same i.e. T
