A man of mass 80kg pushes box of mass 20kg horizontally. The man moves the box with a constant acceleration of `2 m//s^(2)` but his foot does not slip on the ground. There is no friction between the box and the ground. There is no friction between the box and the ground. whereas there is sufficient friction between the man's foot and the ground to prevent him from slipping.
Assertion:- The force applied by the man on the box is equal and opposite to the force applied by the force applied by the box on the man.
Reason:- Friction force applied by the ground on the man is 200N.
