Force on box B are

(i) mBg = WB = its weight, acting downward
(ii) NA = normal force on B due to upper surface of block A, acting upward.

Force on box A are
(i) mAg = WA = its weight, acting downward
(ii) No = normal force on A due to horizontal surface, acting upward.
(iii) NB = normal force on A due to lower surface of block B acting downward.

Two blocks of mass m=5kg and M=10 kg are connected by a string passing over a pulley B as shown. Another string connects the centre of the pulley B to the floor and passes over another pulley A as shown. An upward force F is applied at the centre of pulley A. Both the pulleys are massless. Find the acceleration of both the blocks if 1) F=100N.  2)F=500N

In the arrangement shown in the figure, a heavy pulley of mass M is suspended from a spring of stiffness constant K and the mass m is suspended from a string tightly wound on the pulley. If the mass m is given a small downward displacement and released, find the time period of small oscillations (Take pulley as Disc) and string does not slips on the pulley.

Find the force required to move a load of 100 N up a rough inclined plane, the force being applied parallel to the plane. The inclination of the plane is such that when the same body is kept on a perfectly smooth plane inclined at that angle, a force of 24 N applied at an inclination of 30 degree to the plane keeps the same in equilibrium. Assume coefficient of friction between the rough plane and load equal to 0.3
