Find the acceleration of the 6 Kg block in the figure. All the surfaces and pulleys are smooth. Also, the strings are inextensible and light. [Take g = 10 m/s 2 ]
Text Solution
Verified by ExpertsThe correct answer is:
A
All the blocks will be having the same
acceleration along the length of the string.
So, Applying Newtons law along the string on A, B & C.
⇒ 6g – 2g sin30 
– 2g = (6 + 2 + 2) a
⇒ 3g = 10a ⇒ a = 
Or a = 3 m/s 2
