The magnetic force on a charged particle moving with velocity v is
-
proportional to both the magnitude of the charge and the velocity v
- independent of the magnitude of the charge
- proportional to the velocity v only
- proportional to the magnitude of the charge only
The correct answer is: A
Explanation
The magnetic force on a charge is given byF = qVB SinΞΈ,
thus the force is proportional to both the magnitude by the charge (q) and the velocity (V)
(i/e F Ξ± qV)
