Q: Two block are connected by an ideal string that passes over a pulley of radius R and moment of inertia l. The block of mass m1 slides on a frictionless, horizontal surface and the block of mass m2 is suspended from the string (see figure). Assume that the string does not slip on the pulley. Choose the correct(s).

Numerical

(a) Acceleration of the block is $\frac{2 m_2}{m_1 + m_2 + \frac{1}{R^2}} g $

(b) Acceleration of the block is $\frac{ m_2}{m_1 + m_2 + \frac{1}{R^2}} g $

(c) Tension T1 is $\frac{m_1 m_2 g }{m_1 + m_2 + \frac{1}{R^2}} $

(d) Tension T2 is $\frac{(m_1 + \frac{1}{R^2}) m_2 g }{m_1 + m_2 + \frac{1}{R^2}} $

Ans: (b), (c) , (d)
