The coefficient of friction between 4kg and 5kg blocks is 0.2 and between 5kg blocks and ground is 0.1 respectively. Choose the correct statement :
- a)Minimum force needed to cause system to move is 17N
- b)Maximum acceleration of 4 kg block is 2 m/s2
- c)When force is 4N static friction at all surfaces is 4N to keep system at rest
- d)Slipping between 4kg and 5 kg blocks start when F is 17N
Correct answer is option 'B'. Can you explain this answer?

So block 'Q' is moving due to force while block 'P' due to friction.
Friction direction on both P + Q blocks as shown.
Friction direction on both P + Q blocks as shown.
First block 'Q' will move and P will move with 'Q' so by FBD taking 'P' and 'Q' as system
When applied force is 4 N then FBD
i.e., ap = aq = 0
4 kg block is moving due to friction and maximum friction force is 8 N
So acceleration
Slipping will start at when Q has +ve acceleration equal to maximum acceleration of P i.e., 2 m/s2
The correct answer is: Maximum acceleration of 4 kg block is 2 m/s2

Frictional force between 4kg and 5kg =0.2*N=0.2*mg=0.2*4*10=8N
as we know that f=ma
a=f/m=8N/4kg=2m/sec^2
as we know that f=ma
