Question
In the shown arrangement if f1, f2 and T be the frictional forces on 2 kg block, 3kg block & tension in the string respectively, then their values are:
Options
A.2 N, 6 N, 3.2 N
B.2 N, 6 N, 0 N
C.1 N, 6 N, 2 N
D.data insufficient to calculate the required values.
Solution
FBD
Net force without friction on system is ′7N′ in right side so first maximum friction will come on 3 kg block.
So f2 = 1 N, f3 = 6 N, T = 2N
