Question

If F1 and F2 are the magnetic forces acting on alpha particle and electron respectively, when moving perpendicular to the magnetic field then:
(a) F1=F2
(b) F1>F2
(c) F1 (d) F1=4F2

Answer 1

Answer:

(b) F1>F2

Explanation:

The alpha particle has twice the charge as the electron.

And since the charge on alpha particle is higher, it's magnetic force will also be higher.

So, F1>F2
