Question

The magnetic force acting on a charged particle of
charge -2 uC in a magnetic field of 2 T acting in
y-direction, when the particle velocity (21 +3j) 106
ms-1, is:
[AIPMT (Prelims)-2009]
(1) 4 N in Z-direction
(2) 8 N in y-direction
(3) 8 N in z-direction
- 2 [478
(4) 8 N in -z direction
F-2 (2jir​

Answer 1

Answer:

The particle circulates under the influence of magnetic field. As the magnetic field is uniform, the charge comes out symmetrically. The angle subtended at the center is (180−2θ)
