Assertion : A charge particle is released from rest in a magnetic field then it will move in circular path. Reason : Work done by a magnetic field on the charged particle is non zero.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

D. If both assertion and reason are false.

Step-by-step solution

Magnetic force on a charge particle, F⃗=q(v⃗×B⃗)\vec{F}=q(\vec{v} \times \vec{B}) If v=0v=0 then F=0F=0
