Question

In the system shown in the figure mA=4m,mB=3m and mC=8m.Friction is absent everywhere .String is light and inextensible.If the system is released from rest find the acceleration of the block B​

Answer 1

Answer:

Explanation:

When system is released from the position of rest thenfollowing arethe eqns of motion, 4a=4g−T−−−−(1)and T=3a−−−−−−(2)On adding eqns (1) and (2), we get, 7a = 4gor a = 4g7≈g2Therefore acceleration of block B is g/2 towads left side.
