Three blocks of masses 3 kg, 6 kg and 1 kg are connected by a string passing over two smooth pulleys attached at the two ends of a frictionless horizontal surface. The acceleration of 3 kg mass is
Text Solution
Verified by ExpertsThe correct answer is:
B
Here T 1 – T 2 = 6a,
T 2 – 1g = and 3g – T 1 = 3a = 3a
Adding of the above three equations give
10a = 3g - 1g = 2g
or a =
