A particle of charge q and mass m is moving with a velocity -2 v i (v 0) towards a large screen placed in Y Z -plane placed at a distance d . If there is a magnetic field B=B₀ k , the maximum value of v for which the particle will not strike the screen is

Options

  1. Aq d B₀ m
  2. Bq d B₀ 2 m
  3. C2 q q d B₀ m
  4. Dq d B₀ 3 m

Correct answer

B. q d B₀ 2 m

Step-by-step solution

The charged particle will not strike the screen, if d R (Radius of path) d m(2 v) B₀ q v q d B₀ 2 m v_ = q d B₀ 2 m
