A cyclotron's oscillator frequency is 'n' and radius of the dees is 'r'. The operating magnetic field (B) for accelerating protons of charge ' $q^{'}$ and kinetic energy of protons produced by the accelerator is respectively ('m' and ' $v$ ' be the mass and velocity of proton)

Options:

Answer:

Solution:

Cyclotron frequency $n = \frac{qB}{2 π m}$ $∴ B = \frac{2 π nm}{q}$ Also, $\frac{mv ^{2}}{r} = q vB ∴ mv^{2} = q vB r$ K.E. $= \frac{1}{2} mv^{2} = \frac{qvBr}{2}$ $K . E . = \frac{1}{2} mv^{2} = \frac{qvBr}{2}$
