Cyclotron frequency of electron when accelerated in 1 T magnetic field is ______ .

A

28 MHz

B

280 MHz

C

2.8 GHz

D

28 GHz

Text Solution

Verified by Experts

The correct Answer is:
D
`B=1T,q=1.6xx10^(-19)C,m=9xx10^(-31)kg`
Frequency of cyclotron `f_(c)=(Bq)/(2pim)`
`f_(c)=(1xx1.6xx10^(-19))/(2xx3.14xx9xx10^(-31))=2.79xx10^(10)Hz`
`=27.9xx10^(9)Hz~~28GHz`
