Moving Charges and Magnetism

  1. Under the influence of a uniform magnetic field, a charged particle moves with constant speed v in a circle of radius R. The time period of rotation of the particle:​​
    1. depends on R and not on v
    2. is independent of both v and R
    3. depends on both v and R ​
    4. depends on v and not on R
Correct Option: B

The time period of the charged particle is given by ​T = 2πm/qB
Thus, time period is independent of both v and R.
