Question

In the shown arrangement if f₁, f₂ and T be the frictional forces on 2 kg block, 3kg block and tension in the string respectively, then their values are:

• A. 2N, 6N, 3.2 N
• B. 2N, 6N, 0N
• C. 1N, 6N, 2N
• D. Data insufficient to calculate the required values

Answer 1

Answer: (C)

1N, 6N, 2N

Answer 2

FBD

$\underset { f _ { \max } = 2 \mathrm {~N} } { 2 \mathrm {~kg} \rightarrow \mathrm { T } } \underset { \mathrm { f } _ { \max } = 6 \mathrm {~N} } { 3 \mathrm {~kg} \rightarrow }$

Net force without friction on system is ‘7N’ in right side so first maximum friction will come on 3 kg block

So f₁ = 1N, f₂ = 6N, T = 2N
