Connected Bodies & Pulleys

Two identical blocks each of mass ' M ' attached to the ends of a massless inextensible string which passes over a pulley with a fixed axis as shown below. A small mass ' mm ' is now placed on the block B. The acceleration with which the two blocks move together is [g = gravitational acceleration]

Show answer and solution

Answer: (a)

  1. Unbalanced weight =(M+m)g−Mg=mg= (M + m)g - Mg = mg; total moving mass =2M+m= 2M + m.
  2. a=mg2M+ma = \dfrac{mg}{2M + m}
  3. So the answer is (a).
