A charged particle moves with velocity `vecv` in a uniform magnetic field `vecB`. The magnetic force experienced by the particle is

A

Always zero

B

Never zero

C

Zero, if `vecB` and `vecv` are perpendicular

D

Zero, if `vecB` and `vecv`are parallel

Text Solution

Verified by Experts

The correct Answer is:
D
`vecF=q(vecvxxvecB), if vecv||vecB then vecF=0`
