Question

A boy pushes a box kept on table with 20n force between the surface of the box and table is 12N,what would be the net force acting on the object??
answer fast I will mark as brainliest

Answer 1

Answer:

08 N

Explanation:

Let the boy push the book in forward direction.Now,in which direction friction(force between book and the table) will apply a force ?

• Friction prevents relative slipping between two surfaces.

• But the book is slipping on the table in the forward direction.

• Therefore,friction should apply a force in the backward direction.

Hence,

Force on book in forward direction = 20 N

Force on book in backward direction = 12 N.

Net force = $F_{forward}\: - \: F_{backward}$

= 20 - 12

= 8 N

Hence,net force on the book would be 8 N in the forward direction.

Answer 2

Answer:

8N
