Question 10 of 10 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! Part 1 A particle with mass M and charge +e and its antiparticle (same mass M, charge-e) are initially at rest, far from each other. They attract each other and move toward each other.
