Question

Neha has to push a light box and Sohit has to push a comparatively heavier box made of same material, on the same horizontal floor. What can we say about the forces applied by them?

• A. Neha will have to apply a larger force.
• B. Sohit will have to apply a larger force.
• C. Both will have to apply the same amount of force.
• D. Both of them don't need to apply any force to move the box.

Answer 1

The correct option is B

Sohit will have to apply a larger force.

Frictional force depends on the force with which the surfaces are pressed against each other. Heavier the object, more will be the pressing force and more will be friction. This will require a larger force to overcome friction. As Sohit is pushing a heavier box on the same surface, he will have to apply a larger force.
