A block of mass 1 kg is connected by a light string passing over two smooth pulleys placed on a smooth horizontal surface as shown. Another block of 1 kg is connected to the other end of the string then acceleration of the system and tension in the string are
Text Solution
Verified by ExpertsThe correct answer is:
A
Considering free body diagram,
mg – T = ma (for hanging mass)
and T = ma
(for mass lying on surface)
Adding mg = (m + m) a
or a = mg/2m
∴ ∴ a = 
and T = 1 × 5 = 5 N
