## Sir  Pl solve question no-3

Asked by shobhit 14th May 2018 8:52 AM

## Assertion :- In case of rolling without sliding, friction force can act in forward and backward direction both. Reason :- The angular momentum of a system will be conserved only about that point about which external angular impulse is zero.

## Block A weight 4N and B weight 8N . The coefficient of kinetic friction is 0.25 for all surface. Find the force F to slide B weight a constant.speed when A.rests on B and moves with it find the force F to slide B a constant speed when A is held rest and find the force F to.solid.B at a constant speed when A and B are connected by a light cord passing over a.smooth pulley?
