1. The problem statement, all variables and given/known data Two protons are released from rest, one from location 1 and another from location 2. When these two protons reach location 3, the first proton has a speed that is 4 times the speed of the second proton. If the electric potentials at locations 1 and 2 are 231 V and 115 V, respectively, what is the electric potential at location 3? 2. Relevant equations V =kq/r ? 3. The attempt at a solution I honestly don't know where to start. I feel like I have way too few pieces of information.
