You are tossing a ball directly up into the air. Before the ball leaves your hand, you are exerting a force directed against the force of gravity. If you apply a net force of 10 N to a 1 kg ball, what is the normal force acting on the ball?

F n = 0.2 N

Explanation:

given,

you are exerting force of 10 N on the ball.

mass of the ball = 1 kg

acceleration due to gravity = 9.8 m/s²

normal force on the ball = ?

normal force is force exerted by the object to counteract the force from other object.

normal force acting on the ball will be

F n = F - mg

F n = 10 - 1 * 9.8

F n = 10 - 9.8

F n = 0.2 N

Hence, normal force acting on the ball is equal to 0.2 N
