Physics - EM Waves Question with Solution | TestHub

The proton of energy $1\mathrm{MeV}$ describes a circular path in plane at right angles to a uniform magnetic field of $6.28\times 10^{-4}\mathrm{T}$. The mass of the proton is $1.7\times 10^{-27}\mathrm{Kg}$. The cyclotron frequency of the proton is very nearly equal to
