Question

The coefficient of static friction,

μ s , between block A

of mass 2 kg and the table as shown in the figure is

0.2.

What would be the maximum mass value of block

B

so that the two blocks do not move? The string and the pulley are assumed to be smooth and massless.

( g = 10 m/s 2 ) A 2.0 kg B 4.0 kg C 0.2 kg D 0.4 kg Open in App Solution

The correct option is B 0.4 kg

Free body diagrams of two masses are We get equations T − f = m A a a n d f = μ N = μ m A g ⇒ T = m A a + μ m A g a n d T = m B g ( f o r a = 0 ) ∴ μ N = m B g ⇒ m B = μ m A = 0.2 × 2 = 0.4 kg .

Hence, the correct answer is option (d).

Correct option is C)

The mass of the block A is 2kg, the coefficient of friction is 0.2.

As the blocks do not move therefore, the tension in the string must be equal to the force of friction on block A.

Applying Newton's second law for block A,

T=μ s ​ m A ​ g =0.2×2×10 =4N

Applying Newton's second law for block B,

T=m B ​ g 4=m B ​ ×10 m B ​ =0.4kg

Thus, the maximum mass of the block B is 0.4kg.
