A boy pushes a wall with a force of `20N`. What is the magnitude and direction of the force experienced by the boy?

Text Solution

Verified by Experts

According to Newton's third law of motion,
force exerted by wall on boy = - force exerted by boy on the wall = `-20N`
Negative sign shows that force exerted on the boy is directed away from the wall.
