In the shown arrangement if `f_(1),f_(2)` and `T` be the frictional forces on `2 kg` block, `3 kg` block & tension in the string respectively, then their values are:

A

2 N , 6 N , 3.2 N

B

2 N , 6 N , 0N

C

1N , 6N , 2 N

D

data insufficient to calculate the required values

Text Solution

Verified by Experts

The correct Answer is:
C
FBD
Net force without friction on system is 7 N in right side so first maximum friction will come on 3 kg block .
