The cyclotron frequency of an electron grating in a magnetic field of `1 T` 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
Cyclotron frequency `v = (Bq)/(2pi m)`
`implies v = (1xx1.6xx10^(-19))/(2xx3.14xx9.1xx10^(-31)) = 2.79xx10^(10) Hz`
`= 27.9xx3.14xx9.1xx10^(9) Hz = 28 GHz`
