1. The problem statement, all variables and given/known data
Two identical particles of mass M are moving at speeds V/2 in parallel planes in opposite directions. As they approach each other they experience an attractive force with magnitude $$F = A/r^5$$ where A is a positive constant and r is the distance between them. Find the scattering angle theta.

2. Relevant equations

Here's a diagram I drew:

3. The attempt at a solution

I know I have to set up some sort of integral, but I don't know how to get started in modelling it. Could someone help me set it up?
