Two blocks of mass m=5kg and M=10kg 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 300N are my doubt is that won't the acceleration of M also affect m's acceleration?

As g is constantly applied

Best answer

T=F/4=75

T<Mg and T>mg, M will be remain stationary on the floor,whereas m will move

Acceleration of m,

a=(T-mg)/m=(75-50)/5 = 5m/s2..

Option a is correct
