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 – proportional to both the magnitude of the charge and the velocity v
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)
