A charged particle is moving in a cyclotron, what effect on the radius of path of this charged particle will occur when the frequency of the radio frequency field is doubled?

Options

A. It will also be doubled.
B. It will be halved.
C. It will be increased by four times.
D. It will remain unchanged.

Answer

D

Explanation

As frequency of revolution in a cyclotron `upsilon_(C)=(Bq)/(2pi m)` is independent of r.
So the radius of path in the dees will remain unchanged. When the frequency is changed.
