Problem: A proton with kinetic energy K=0.2eV is moving toward the right and parallel to the x-axis. The proton is initially a long distance to the left of the origin and at y=1.35 nm above the x-axis.
Part A: If there is fixed proton at the origin, how close does the moving proton get to the fixed proton? (Hint-you'll need to conserve energy and angular momentum!)
I need help to find how close the moving proton gets to the fixed proton.
