The cyclotron frequency of an electron gyrating in a magnetic field of `1T` is approximately:

A

28 MHz

B

280 MHz

C

2.8GHz

D

28 GHz

Text Solution

Verified by Experts

The correct Answer is:
D
Cyclotron frequency `v(qB)/(2pim)=(1.6xx10^(-19)xx1)/(2xx3.14xx9.1xx10^(-31))`
`28xx10^(9)Hz=28 GHz`
