A positive charge particle of charge q, ...

A positive charge particle of charge q, mass m enters into a uniform magnetic field with velocity v as shown in the figure. There is no magnetic field to the left of PQ. Find

distance travelled in the magnetic field

Text Solution

Verified by Experts

The particle will move in the field as shown. Angle subtended by the arc at the centre = `2theta`
Distance travelled by the charge in magnetic field :
`=r(2theta)=(mv)/(qB).2theta`
