Answer 2

Answer:

$\rightarrow$The force of friction between the two surfaces will increase if the two surfaces are pressed harder against each other. Heavy box will press the floor surface harder as compared to the lighter box. ... Thus, larger force will be needed to push the heavier box than to push the lighter one
