Two blocks of mass 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. Draw the free body diagrams of (a) pulley A (b) pulley B.

Answer:

F.B.D of the pulley a F = Applied force shown \[{{T}_{1}}=\]Tension in the rope passing through in the pulley A shown F.D.B of the pulley B. \[{{T}_{1}}=\]Tension in the rope connecting the pulley A and the pulley B shown. Which is equal to\[\frac{F}{2}.\] \[{{T}_{2}}=\]Tension in the rope passing in the pulley B which is equal to \[\frac{{{T}_{1}}}{2}\]
