The operating magnetic field for accelerating protons in a cyclotron oscillator having frequency of 12 MHz is `(q= 1.6 xx 10^(-19) C, m_(p) = 1.67 xx 10^(-27) kg and 1 MeV = 1.6 xx 10^(-13J))`

A

0.69T

B

0.79T

C

0.59T

D

0.49T

Text Solution

Verified by Experts

The correct Answer is:
B
`B=(2pi m_(p)upsilon)/(q)`
`=(2xx3.14xx1.67xx10^(-27)xx12xx10^(6))/(1.6xx10^(-19))=0.79T`
