Question

Two blocks each of mass m lie on a smooth table. They are attached to two other masses as shown in the figure. The pulleys and strings are light. An object O is kept at rest on the table. The sides AB & CD of the two blocks are made reflecting. The acceleration of two images formed in those two reflecting surfaces w.r.t. each other is:

  1. 5g / 6    
  2. 5g / 3    
  3. g / 3    
  4. 17g / 6    

The correct answer is: 17g / 6
