AIPMT PRELIMS 2004 Physics Static Friction MCQ Question

Type: MCQ-numerical-Medium-Class 11

The coefficient of static friction, μₛ, 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/s²)

Question diagram
A

4.0 kg

B

0.2 kg

C

0.4 kg

D

2.0 kg

Correct Answer

Option C

Detailed Explanation

The maximum static friction force is calculated and equated to the gravitational force on block B to find its maximum mass.
