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

Options

  1. A3 T
  2. B2 T
  3. CT
  4. D4 T

Correct answer

C. T

Step-by-step solution

After passing through a magnetic field, the magnitude of its mass and velocity of the particle remain same, so its energy does not change, ie., kinetic energy will remain T .
