Hi, can anyone solve this with a detailed explanation.   The electron in a hydrogen atom is initially at a distance  2.12 Å from the proton, and then moves to a distance  0.529 Å from the proton. (a) Calculate the change in the force between the proton  and the electron. (b) Calculate the change in the potential energy between  the proton and the electron. (c) Calculate the change in the velocity of the electron.
