The magnetic force on a charged particle moving with velocity v is
-
A.
proportional to both the magnitude of the charge and the velocity v -
B.
independent of the magnitude of the charge -
C.
proportional to the velocity v only -
D.
proportional to the magnitude of the charge only
Correct Answer: Option A
Explanation
The magnetic force on a charge is given by
F = qVB Sinθ,
thus the force is proportional to both the magnitude by the charge (q) and the velocity (V)
(i/e F α qV)
