A block of mass 1.0 kg rests on a wedge of angle theta . The acceleration which should be given to the wedge so that the block falls freely is :

A block of mass 1.0 kg rests on a wedge of angle theta . The acceleration which should be given to the wedge so that the block falls freely is :

A block of mass m is placed on the rough incline of a wedge of mass M and inclination alpha to the horizontal. Calculate the maximum and minimum acceleration that can be imparted to the wedge so that the block may remain stationary relative to the wedge. The coefficient iof friction between the block and the wedge is mu .

A cylinder of mass m rests on a supporting block as shown. If beta=60^(@) " and " theta=30^(@) , calculate the maximum acceleration 'a' which the block may be given up the incline so that the cylinder does not lose contact at B. (neglect friction anywhere).

Find out acceleration of the block. Initially the block is at rest.

Find out acceleration of the block. Initially the block is at rest.

Figure shows a block kept on a rough inclined plane. The maximum external force along the plane downwards for which the block remains at rest is 1N while the maximum external force along the incline upwards for which the block is rest is 7N. The coefficient of static friction mu is
