(a) Derive the Magnification of a compound. (b) Two block of masses 8 kg and 2 kg respectively lie ono a smooth horizontal surface in contact with one other. They are pushed by a horizontally applied force of 15 N. calculate the force exerted on the 2 kg mass.

Three blocks A, B and C of mass 4 kg , 2kg and 1kg respectively , are in contact on frictionless surface as shown .If a force appliedon 14N is applied on the 4 kg block then the contact force between A and B is :

A block of mass 2.5 kg is kept on a rough horizontal surface. It is found that the block does not slide if a horizontal force less than 15 N is applied to it. Also it is found that it takes 5 seconds to slide through the first 10 m if a horizontal force of 15 N is applied and the block is gently pushed to start the motion. Taking g=10 m/s^2 , calculate the coefficient of static and kinetic friction between the block and the surface.

Two blocks A and B of mass m_A and m_B respectively are kept in contact on a frictionless table. The experimenter pushes the block A from behind so that the blocks accelerate. If the block A exerts a fore F on the block B, what is the force exerted by the experimenter on A?

If two objects of masses 500 kg and 84 kg respectively are at a distance of 2m apart from each other. Find gravitational force between them?

A block of mass m is placed on a smooth wedge of incination theta . The whole system s acelerated horizontally so tht the block does not slip on the wedge. The force exerted by the wedge on the block has a magnitude
