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

Options

  1. Adepends on v and not on R
  2. Bdepends on R and not on v
  3. Cis independent of both v and R
  4. Ddepends on both v and R

Correct answer

C. is independent of both v and R

Step-by-step solution

The time period of circular motion of the charged particle is given by aligned & T = 2 r v = 2 v mv Bq & T = 2 m Bq aligned Hence, time period of rotation of the charged particle in uniform magnetic field is independent of both v and R .
