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
