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 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

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

A block of mass m is kept on an inclined plane is angle inclination theta ( lt phi), where phi= angle of friction. Then :

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
