Two protons that are very far apart are hurled straight at each other, each with an initial kinetic energy of 0.19 mev, where 1 mega electron volt is equal to 1multiply106 multiply (1.6multiply10-19) joules. what is the separation of the protons from each other when they momentarily come to a stop?

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.
