SUMMARY
An electron starting from rest acquires 3.53 keV of kinetic energy when moving from point A to point B. Due to the principle of conservation of energy, a proton moving from point B to point A will also acquire the same amount of kinetic energy, which is 3.53 keV. The relevant equations include kinetic energy (KE = 1/2 mv²) and the conversion of electron volts to joules (1 eV = 1.6 x 10^-19 J). The masses of the electron (me = 9.11 x 10^-31 kg) and proton (mp = 1.67 x 10^-27 kg) are also critical in understanding the energy dynamics.
