A ball B of mass ‘in' is tied to a 90 cm thread of negligible mass and is pivoted from a rigid point 'O'. The ball B is pulled aside through 60° and then released. When the ball B reaches its lowest position, it collides elastically with another ball P of mass '2m' at rest on a rough horizontal table of coefficient of kinetic friction 0.1. as shown in the frame. After collision, the ball P travels a distance ‘d' before it comes to rest and the ball B reaches a maximum height ‘h'. Then, the value of (
