In the figure shown all the surfaces are frictionless, and mass of the block 'm' is 1 kg. The block and wedge are held initially at rest. Now wedge is given a horizontal acceleration of 5 m/s^(2) 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 2 sec is : (##NAR_NEET_PHY_XI_P2_C06_E09_012_Q01.png" width="80%">
