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 and CD of the two blocks are plane and made reflecting. The acceleration of two images formed in those two reflecting surfaces with respect to each other is –
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Acc. of block AB = 
Acc. of block CD = 
Acc. of image in mirror AB = 2 × acc. of mirror
2 × 
Acc. of image in mirror CD = 2 × 
elative acceleration = 
=
