There are two protons of a helium atom seperated by 1.00e-15m
(a) If the protons were allowed to move, what would be their initial acceleration due to the electric force between them? Recall Newton's 2nd Law: a = F/m.
b) Assuming the protons were allowed to move and they began their motion at rest, what would be their speed once they are very far apart, i.e. when their electrostatic potential energy is assumed to be zero?
