Question

The relation between force on a moving charged particle and the period of rotation of the particle will be:​

Answer 1

Answer:

When the velocity of a charged particle is perpendicular to the uniform magnetic field B, the particle moves in a plane perpendicular to B. This motion is known as cyclotron. Here magnetic force required to keep the particle moving in a circle.

So, F

B

=qvB=

r

mv

2

or r=mv/qB

The period of revolution, T=

v

2πr

=

qB

2πm

Thus, the period of revolution does not depend on velocity, v.
