Question

Two blocks of masses m $$=$$ $$5$$ kg and M $$=$$ $$10$$ kg are connected by a string passing over a pulley B as shown. Another string connects the centre of 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. The accelerations of blocks m and M, if F is $$300$$ N are (Take$$, g $$=$$ $$10$$ $$ms-2)

Infinity Learn · Accepted Answer

$$F4=75$$ N or $$F4$$<$$100$$ NTherefore,   $$aM=0$$,$$am=75-505=5$$ $$m/s2$$
