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 = *qv*B sin *θ*

*θ *= Angle between direction of motion and magnetic field.

If *θ* = 90°

F_{1} = *qv*B sin 90° = *qv*B

If *θ* = 30°

F_{2} = *qv*B sin 30°

We know angular frequency

Angular frequency does not depend on *θ.*

So, ratio of frequencies
