Arrows represent the forces applied to an object. A longer arrow means a greater force. Which object will move upward?
Katen [24]

Answer:

Object C

Explanation:

Object A has two arrows, one pointing up and one pointing down. Since both arrows are the same length, the forces cancel, and Object A will not move.

Object B also has two arrows, one pointing up and one pointing down. However, the downwards pointing arrow is much longer than the other. This means it has more force and the object will move down.

Object C has two arrows, one pointing up and the other down. However, the upwards pointing arrow is longer than the other, meaning it has more force and the object will move upward.

Object D has two arrows, but both are pointing downwards, meaning the object will move down.
