no explanation ?
A charge particle X moves directly towards another charged particle Y. for the ‘X and Y’ system, the total moment is ‘p’ and the total energy is ‘E’.
a) p and E are conserved if both X and Y are free to move.
b) (a) is true only if X and Y have similar charges.
c) if Y is fixed, E is conserved but not ‘p’.
d) if Y is fixed, neither E nor p is conserved.
