A proton (1e) and an alpha particle charge = 2e, mass = 6.64 x10^-27 kg are initially at rest, separated by 4.00 x 10^-15 m. If they are both released simultaneously, explain why you can't find their velocities at infinity using only conservation of energy.What other conservation law can be applied in this case? Find the speeds of the proton and alpha particle respectively, at infinity.
