A block of mas m begins to slide down on an inclined plane of inclination theta . The force of friction will be

A block of mass m is placed on a rough inclined plane of inclination theta kept on the floor of the lift. The coefficient of friction between the block and the inclined plane is mu . With what acceleration will the block slide down the inclined plane when the lift falls freely ?

A block is released on an smooth inclined plane of inclination theta . After how much time it reaches to the bottom of the plane?

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 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 smooth inclined plane of angle of inclination 30^(@) is placed on the floor of a compartment of a train moving with a constant acceleration a. When a block is placed on the inclined plane, it does not slide down or up the plane. The acceleration a must be
