Question

A Uniform rod A B is hinged at its end A and the other end of the rod is connected to a block through a massless string as shown in the figure. The pulley is smooth and massless. Masses of the block and the rod are same and are equal to m . The acceleration of the block just after the release from this position is, 6 g 13, g 4, 3 g 8, N o n e

For the rod: T ℓ - mg ℓ 2 = m ℓ 2 3 × a ℓ ...(i) For the: m g - T = m a ...(ii) Solving (i) and (ii) we get: a = 3 g 8
