A block is kept on a frictionless inclined surface with angle of inclination alpha . The incline is given an acceeration 'a' to keep the block stationary Then 'a' is equal to .

A block mass 'm' is placed on a frictionless inclined plane of inclination theta with horizontal. The inclined plane is accelerated horizontally so that the block does not slide down. In this situation vertical force exerted by the inclined plane on the block is:

A block is kept on a smooth inclined plane of angle of inclination theta that moves wuth a contact acceleration so that the block does not slide relative to the inclined plane. If the inclined plane stops the normal contact force offered by the plane on the block changes by a factor

A block of mass 10 kg is kept on a fixed rough (mu=0.8) inclined plane of angle of inclination 30^(@) . The frictional force acting on the block is

The acceleration of 10 kg block on the inclined plane is

A block of mass m is at rest on a rough inclined plane of angle of inclination theta . If coefficient of friction between the block and the inclined plane is mu , then the minimum value of force along the plane required to move the block on the plane is

A block of mass 5 kg is at rest on a rough inclined surface. If angle of inclination of plane is 60^(@) , then force applied by it on block is
