Solution

The correct options are
B Sohit
D larger
In this case, frictional force depends on the weight of the object which is being pushed on the surface. Heavier the object, larger is the normal force applied on the surface. We know that the magnitude of friction depends on normal force. As both Neha and Rohit are pushing the object made of similar material on the same floor, Rohit will have to apply a greater force as he is pushing a heavier box.
