Question
A particle is moved from (0, 0) to (a, a) under a force 
from two paths. Path 1 is OP and path 2 is OQP. Let 
and 
be the work done by this force in these two paths. Then:
S
- =
- = 2
- = 2
- = 4
=
= 2
= 2
= 4
The correct answer is: =

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 
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 
seconds is:
