QAIPMT-2004-Ph-2651: NEET 2004 Physics - Class 11 AIPMT-2004-Ph-2651 Solution: The coefficient of static friction, \( _s\), between block A of …
The coefficient of static friction, , 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 )
Multiple Choice Options
- A 2.0 kg
- B 4.0 kg
- C 0.2 kg
- D 0.4 kg
Step-by-Step Verified Solution
Free body diagram of two masses is
We get equations
T + m a = f _ or T = _ N A ( f o r a = 0 )
and T = ma + mg or T = m B g (for a = 0)
_ _ N A = m B g
_ m B = _ m A = 0.2 _ 2 = 0.4 k g
