(B) The kinetic energy $(KE)$ gained by a charged particle accelerated through a potential difference $(V)$ is given by the formula: $KE = qV$.Here,the charge of the proton is $q = 1.6 \times 10^{-19} \,C$.The potential difference is $V = 1 \text{ million volts} = 10^6 \,V$.Substituting these values into the formula:$KE = (1.6 \times 10^{-19} \,C) \times (10^6 \,V)$$KE = 1.6 \times 10^{-13} \,J$.Thus,the kinetic energy gained by the proton is $1.6 \times 10^{-13} \,J$.
