Identify the correct statement from thee following.

Options

A. Cyclotron frequency depends upon the speed of the charged particle
B. Cyclotron frequency does not depends upon the speed of charged particle
C. Kinetic energy of a charged particle in a cyclotron is independent of its charge
D. Kinetic energy of a charge particle in a cyclotron is independent of its mass

Answer

B

Explanation

(b) is the correct statement.Cyclotron frequency,`n=(qB)/(2pim)`. It does not depend upon v.Similarly `E=(q^(2)B^(2)r^(2))/(2m)`. It depends upon q and m.
