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
Verified Correct Answer: A.
Physical Principles & Numerical Solution
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)
