This is a challenging problem. Solve it on paper, writing out each step carefully. When doing calculations, do not round intermediate values. Note: If you have approached the problem in a principled way, do not abandon your approach if your numerical answer is not accepted; check your calculations! Four protons (each with mass 1.7 Γ 10-27 kg and charge 1.6 Γ 10-19 C) are initially held at the corners of a square that is 5.0 Γ 10-9 m on a side. They are then released from rest. What is the speed of each proton when the protons are very far apart? (You may assume that the final speed of each proton is small compared to the speed of light.)
