Explanation Given: Potential difference applied, Δ V = 9 V Mass of an electron, m = 9.1 × 10 − 31 kg Charge of the electron, q = − 1.6 × 10 − 19 C Mass of a proton, m = 1.67 × 10 − 27 kg Charge of the proton, q = 1.6 × 10 − 19 C Formula used: The relation between potential energy and potential difference is as follows U = q Δ V Here, U is the potential energy q is the charge ofparticle Δ V is the potential difference The kinetic energy of the proton is calculated as K E = 1 2 m v 2 Here, m is the mass of particle v is the velocity of the particle Calculation: (a) For proton: Calculate the potential energy of the proton U = q Δ V Plugging the value in the above equation U = 1.6 × 10 − 19 × 9 = 14.4 × 10 − 19 J According to the energy conservation, all the potential energy is converted into the kinetic energy K E initial − K E final = U 1 2 m p v initial 2 − 1 2 m p v final 2 = U Plugging the value in the above equation 1 2 × 1.67 × 10 − 27 × 0 − 1 2 × 1.67 × 10 − 27 × v 2 = 14.4 × 10 − 19 J 0 − 1 2 × 1.67 × 10 − 27 × v 2 = 14.4 × 10 − 19 J v = 14
