A) depends on v arid not on R
B) depends on R and not on v
C) is independent of both v and R
D) depends on both v and R
Correct Answer: C
Solution :
| [c] The time period of circular motion of the charged particle is given by |
| \[T=\frac{2\pi r}{v}=\frac{2\pi }{v}\times \frac{mv}{Bq}\] |
| or \[T=\frac{2\pi m}{Bq}\] |
| Hence, time period of rotation of the charged particle in uniform magnetic field is independent of both v and R. |
