268635 Two spheres ' \(X\) ' and ' \(Y\) ' collide. After collision, the momentum of \(X\) is doubled. Then

1 the initial momentum of \(X\) and \(Y\) are equal
2 the initial momentum of \(X\) is greater then that of \(\mathrm{Y}\)
3 the initial momentum of \(Y\) is double that of \(X\)
4 the loss in momentum of \(\mathrm{Y}\) is equal to the initial momentum of \(X\)
