Let mA and mB be the mass of blocks A and B respectively.
As the force F increases from 0 to µs mAg, the frictional force f on block A is such that f = F. When F = µsmAg, the frictional force f attains maximum value f = µsmg.
As F is further increased to µs(mA + mB)g, the block A does not move. In this duration frictional force on block A remains constant at µsmAg.
As F further increased, system will start moving and kinetic friction (µxAg) will start acting on A (µs>µk). Hence C is correct choice.
The correct answer is:
As the force F increases from 0 to µs mAg, the frictional force f on block A is such that f = F. When F = µsmAg, the frictional force f attains maximum value f = µsmg.
As F is further increased to µs(mA + mB)g, the block A does not move. In this duration frictional force on block A remains constant at µsmAg.
As F further increased, system will start moving and kinetic friction (µxAg) will start acting on A (µs>µk). Hence C is correct choice.
The correct answer is:
