1. The problem statement, all variables and given/known data If two protons start out at rest relative to each other, separated by 0.1 nanometers in vacuum, and then they are released, calculate their relative positions after 10 seconds. 2. Relevant equations F = (kq^2)/r^2 = m*a 3. The attempt at a solution I am fairly certain this needs to be solved using an integral since the force is constantly changing with the distance between the two protons, but I'm quite confused what it would have respect to. Time perhaps, ranging from 0 to 10 seconds and using a = dv/dt.
