The drawings show three examples of the force with which someone pushes against a vertical wall. In each case the magnitude of the pushing force is the same. Rank the normal forces that the wall applies to the pusher in ascending order (smallest first).

Complete Question

The complete question is shown on the

The ascending order would be 2nd < 1st < 3rd

Explanation:

Generally the the Normal force is mathematically represented as

=>                    

For the first drawing  the value   is between that of the the second and the third drawing so the Normal force would also be between the normal forces of the second and the third drawing

For the second drawing whose value of is less than that of the first and the third the normal force would also be less than that of the first and third

For the the third drawing whose value is (90°) which is higher than the first and the second the normal force would also be higher than the first and the second

drawing 2< drawing 1 < drawing 3

Explanation:

Complete Question is:

The drawings(attachment) show three examples of the force with which someone pushes against a vertical wall. In each case the magnitude of the pushing force is the same. Rank the normal forces that the wall applies to the pusher in ascending order (smallest first)

1st drawing is a medium angle

2nd drawing is a small angle

3rd drawing is a large angle (almost 90 degrees and perpendicular to the wall)

Normal Force= Fsinθ

Here is θ is the angle between the wall and the force applied that is F.

As θ increases, value of sinθ increases. When θ is 90, sinθ is maximum that is 1 and value of resultant.

Therefore, normal force is greatest in diagram 3 and least in diagram 2
