Question

In the figure shown all the surfaces are frictionless, and mass of the block, m = 1 kg. The block and wedge are held initially at rest. Now wedge is given a horizontal acceleration of 10 m/s2 by applying a force on the wedge, so that the block does not slip on the wedge. Then work done by the normal force in ground frame on the block in square root of 3 seconds is

  1. 30 J    
  2. 60 J    
  3. 150 J    
  4. 100 square root of 3 J    

The correct answer is: 150 J
