two people push on the same door from opposite sides as shown. they will only see the door move when\n○ both people exert the same force so that the forces are unbalanced.\n○ neither person exerts a force on the door so that the net force is zero.\n○ one person exerts more force than the other so that the forces are unbalanced.\n○ both people exert the same force so that the forces are balanced.

two people push on the same door from opposite sides as shown. they will only see the door move when\n○ both people exert the same force so that the forces are unbalanced.\n○ neither person exerts a force on the door so that the net force is zero.\n○ one person exerts more force than the other so that the forces are unbalanced.\n○ both people exert the same force so that the forces are balanced.

Answer

Brief Explanations:

When forces acting on an object are balanced (equal in magnitude and opposite in direction), the net force is zero and the object remains at rest or in uniform - motion. For an object to start moving or change its motion, there must be an unbalanced force. In the case of the door, when one person exerts more force than the other, the forces are unbalanced and the door will move.

Answer:

one person exerts more force than the other so that the forces are unbalanced.
