A body of mass 2 kg rests on a rough inclined plane making an angle of 30^(@) with the horizontal. The coefficient of static friction between the block and the plane is 0.7. The frictional force on the block is :

A 1 kg block situated on a rough incline is connected to a spring of spring constant 100 Nm^(-1) as shown in Fig. 6.17. The block is released from rest with the spring in the unstreched position. The block moves 10 cm down the incline before coming to rest. Find the coefficient of friction between the block and the incline. Assume that the spring has a negligible mass and the pulley is frictionless.

A block rests on a rough inclined plane making an angle of 30 ^@ with the horizontal . The coefficient of static friction between the block and the plane is 0.8 If the frictional force on the block is 10 N the mass of the block is " "(g=10 ms ^(-2))
