Jose and gina are studying balanced and unbalanced forces and are challenged to test their theories. predict the result when jose applies 6 newtons of forces to one side of a box and gina applies 6 newtons of force to the other side of the box.

a)
the box does not move.

b)
the box moves toward gina.

c)
the box moves toward jose.

d)
the force crumples the box.

Answer : The correct option is, (A) The box does not move.

Explanation :

Force : It is defined as the force can be a push or a pull.

Balanced force : When the two forces are equal in magnitude and in opposite direction. These forces are balance to each other. In this force, the object does not move.

Unbalanced force : When the two forces are not equal in magnitude and direction. These forces does not balance to each other. In this force, the object will move on that side where the force will be applied more.

There are three cases :

Case 1 :

That means, when the force applied from left side are equal to the force applied from the right side then they balance to each other and object will not move.

Case 2 :

That means, when the force applied from left side are more than the force applied from the right side then the object will move towards right side.

Case 3 :

That means, when the force applied from left side are less than the force applied from the right side then the object will move towards left side.

According to question, the applied forces are equal in magnitude and in opposite direction. So, the box will not move.

Therefore, the correct answer is, A

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
