The time period for proton will be higher

(B) The time period $T$ of a charged particle moving in a uniform magnetic field $B$ is given by the formula $T = \frac{2\pi m}{qB}$.Since the charge magnitude $q$ (for both proton and electron) and the magnetic field $B$ are the same,the time period is directly proportional to the mass of the particle,i.e.,$T \propto m$.We know that the mass of a proton $(m_p)$ is significantly greater than the mass of an electron $(m_e)$,i.e.,$m_p > m_e$.Therefore,the time period of the proton will be greater than the time period of the electron.
