Two blocks each of mass \( m \) lie on a smooth table. They are attached to two other masses as shown in the figure-5.342.
The pulleys and strings are light. An object \( O \) is kept at rest on the table. The sides \( A B \& C D \) of the two blocks are made reflecting. The acceleration of two images formed in those two reflecting surfaces w.r.t. each other is:
Figure \( 5.342 \)
(A) \( 5 g / 6 \)
(B) \( 5 g / 3 \)
(C) \( g / 3 \)
(D) \( 17 g / 6 \)
