Two blocks are connected by a massless string through an ideal pulley as shown. A force of 22N is applied on block B when initially the blocks are at rest. Then speed of center of mass of block A and block B, 2 sec, after the application of force is (masses of A and B are 4 kg and 6 kg respectively and surfaces are smooth) –
Text Solution
Verified by ExpertsThe correct answer is:
A
F – 2T = 6a and T = 4 × 2a
F – 16 a = 6a
a = 
a = 1m/s 2 a CM = 
= 1.4 m/s
