A block of `3 kg` rests in limiting equilibrium on an inclined plane of inclination `30^(@)`. If the plane is raised to an inclination `60^(@)` , the force along the plane required to support it is

For the equilibrium of a body on an inclined plane of inclination 45^(@) , the coefficient of static friction will be

A thin uniform circular ring is rolling down an inclined plane of inclination 30^(@) without slipping. Its linear acceleration along the inclined plane is :

A block of mass 4kg rests on an an inclined plane. The inclination of the plane is gradually increased. It is found that when the inclination is 3 in 5 (sin=theta(3)/(5)) the block just begins to slide down the plane. The coefficient of friction between the block and the plane is.

A block of mass m = 2kg is resting on a inclined plane of inclination 30^(@) as shown in figure The coefficient of friction between the block and the plane is mu = 0.5 what minimum force F (in newton) should be applied perpendicular to the plane on the block so that the does not slip on the plane?

A block of mass 10kg is pushed up on a smooth incline plane of inclination 30^(@) , so that it has acceleration 2m//s^(2) . The applied force is

A uniform thin hemispherical shell is kept at rest and in equilibrium on an inclined plane of angle of inclination theta=30^(@) as shown inf figure. If the surface of the inclined plane is sufficiently rough to prevent sliding then the angle alpha made by the plane of hemisphere with inclined plane is :

A block of mass 4 kg is pulled along a smooth inclined plane of inclination 30^(@) with constant velocity 3 m/s as shown, power delivered by the force is
