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

A

28 MHz

B

280 MHz

C

2.8 GHz

D

28 GHz

Text Solution

Verified by Experts

The correct Answer is:
D
`f = (qB)/(2pi m) = (1.6 xx 10^(-19) xx 1)/(2 xx 3.14 xx 9.1 xx 10^(-31))`
`implies f = 2.8 xx 10^(10)` Hz = 28 GHz.
