A cyclotron's oscillator frequency is 20 MHz . The operating magnetic field for accelerating protons is (charge of proton =1.6 10⁻¹⁹ C , mass of proton =1.67 . x 10⁻²⁷ ~kg )
Options
- A0.66 ~T
- B1.1 ~T
- C0.33 ~T
- D1.31 ~T
Correct answer
D. 1.31 ~T
Step-by-step solution
We have aligned & R = mv qB = mR qB B = m 2 f q & = 1.67 10⁻²⁷ 2 3.14 20 10^6 1.6 10⁻¹⁹ =1.31 ~T aligned
