1. The problem statement, all variables and given/known data An electron is held fixed at a distance of 1 m from the nucleus of a uranium atom (Z = 92). If the electron is then released, what is the magnitude of its initial acceleration? 2. Relevant equations I am not sure which kinematic equation that I should use. 3. The attempt at a solution This is the only problem on my physics final review that I do not know how to do. I know that the answer is 23,300 m/s^2, but I do not know how to get this answer. I would really love it if someone could explain how to solve this to me.
