Question

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

Minimum force needed to cause system to move is 17 N
When force is 4N static friction at all surfaces is 4N to keep system at rest
Maximum acceleration of 4kg block is $2 m / s^{2}$
Slipping between 4kg and 5 kg blocks start when F is 17N

The correct answer is: Maximum acceleration of 4kg block is $2 m divided by s to the power of 2 end exponent$

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 $m divided by s to the power of 2 end exponent$ 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 $square root of 3 blank$ seconds is:
