A charge ' q _ ^ moving with velocity ' v 'in a magnetic field of induction B , experiences force F '. The angle between v and B is . The speed of ' q _ ' after one second will be

Options

  1. Av / B
  2. Bv
  3. Cv B
  4. DB / v

Correct answer

B. v

Step-by-step solution

The magnetic force does not change the magnitude of the velocity as it acts right angles to the velocity.
