The magnetic force acting on a charged particle of charge – 2 µC in a magnetic field of 2T acting in y direction, when the particle velocity is (2î + 3ĵ) × 106ms-1,is
-
- 4 N in z direction
- 8 N in y direction
- 8 N in z direction
- 8 N in – z direction
Correct Option: D
The magnetic force acting on the charged paraticle is given by
→F = (→v × →B)
= (–2× 10–6) = [{2î + 3ĵ) × 106} × (2ĵ)]
= -4(2̂k)
= - 8̂k
∴ Force is of 8N along – z-axis.
