two identical charged particles moving with same speed enter a region of uniform magnetic field. if one of these enters normal to the feild direction and the other along a direction at 30'c with the field , what would be the ratio of their angular frequencies?

Force on moving charge particle in a magnetic field (uniform)

F = qvB sin θ

θ = Angle between direction of motion and magnetic field.

If θ = 90°

F1 = qvB sin 90° = qvB

If θ = 30°

F2 = qvB sin 30°  

We know angular frequency

Angular frequency does not depend on θ.

So, ratio of frequencies
