Question

The coefficient of friction between 4kg and 5 kg blocks is 0.2 and between 5kg block and ground is 0.1 respectively. Choose the correct statements

  1. Minimum force needed to cause system to move is 17N    
  2. When force is 4N static friction at all surfaces is 4N to keep system at rest    
  3. Maximum acceleration of 4kg block is 2m/s2    
  4. Slipping between 4kg and 5 kg blocks start when F is 17N    

The correct answer is: Maximum acceleration of 4kg block is 2m/s2
