The positively charged particles X and Y are initially far away from each other and at rest X begins to move towards Y with some initial velocity The total momentum and energy of the system are p and E 1 If Y is fixed both p and E are conserved 2 If Y is fixed E is conserved but not p 3 If both are free to move p is conserved but not E 4 If both are free E is conserved but not p
