Question

An alternating electric field, of frequency v, is applied across the dees (radius = R) of a cyclotron that is being used to accelerate protons (mass = m). The operating magnetic field (B) used in the cyclotron and the kinetic energy (K) of the proton beam, produced by it, are given by
(a) $B=\frac{mv}{e}\ and\ K=2m\pi^{2}v^{2}R^{2}$
(b) $B=\frac{2\pi mv}{e}\ and\ K=m^{2}\pi vR^{2}$
(c) $B=\frac{2\pi mv}{e}\ and\ K=2m\pi^{2}v^{2}R^{2}$
(d) $B=\frac{mv}{e}\ and\ K=m^{2}\pi vR^{2}$
