A charge moves in a circular path perpendicular to a magnetic field. The time period of the revolution is independent of
- A strength of charge.
- B magnetic field.
- C mass of the charge.
- D velocity of the charge.
Answer & Solution
Correct Answer
(D) velocity of the charge.
Step-by-step Solution
Detailed explanation
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.
So, it is independent of velocity.
