Two positively charged particles X and ...

Two 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`.

If Y is fixed , bith P and E are conserved

If Y is fixed, E is conserved nut p is not conserved

If both are free to move , P is conserved but E is not conserved

If both are free , E is conserved , but P is not conserved
