A charge moves in a circular path perpendicular to a magnetic field. The time period of the revolution is independent of
  1. strength of charge.
  2. magnetic field.
  3. mass of the charge.
  4. velocity of the charge.

Solution

The time period of a charged particle undergoing circular motion under uniform perpendicular magnetic field is given by $T=\frac{2 \pi m}{q B}$ So, it is independent of velocity.
