AIPMT PRELIMS 2004 Physics Static Friction MCQ Question
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)
4.0 kg
0.2 kg
0.4 kg
2.0 kg
Correct Answer
Detailed Explanation
The maximum static friction force is calculated and equated to the gravitational force on block B to find its maximum mass.
