A charged particle moves with some initial velocity along the direction of external magnetic field B . Now, if we apply uniform field perpendicular to the magnetic field, then the trajectory of the charged particle will be

Options

  1. Acircle
  2. Bhelix
  3. Ccycloid
  4. Dstraight line

Correct answer

B. helix

Step-by-step solution

As charged particle enters region of electric field, its' net velocity is inclined at some angle to B . So, path of charged particle is a helix.
