Solving time: 2 mins

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 $(g = 10 m / s^{2})$

The mass of the block

A

2 kg

, 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 \times 2 \times 10

= 4 N

Applying Newton's second law for block B,

T = m_{B} g

4 = m_{B} \times 10

m_{B} = 0.4 kg

Thus, the maximum mass of the block B is

0.4 kg
