Rolanda sees an error in her friend’s graphic organizer comparing electrical and gravitational forces.

Question

A Venn diagram with two intersecting circles. The circle on the left is labeled gravitational force. The circle on the right is labeled electrical force. There is an X in the circle on the left with infinite reach and depends on mass. In the circle on the right is Z with depends on charge. There is a Y in the intersecting area.
Which change should Rolanda suggest to her friend to correct the error?

The note about mass belongs in region Z, and the note about charge belongs in region X.
The note about mass belongs in region Y, and the note about infinite reach belongs in region Z.
The note about charge belongs in region Y.
The note about infinite reach belongs in region Y.

Answer 1

To correct the error in the graphic organizer comparing electrical and gravitational forces using a Venn diagram, Rolanda should suggest that the note about infinite reach belongs in region Y.

Here's the reasoning:

1. Gravitational Force: This force acts between masses and has infinite reach, meaning it can act over an infinite distance.
2. Electrical Force: This force acts between charged particles and is dependent on charge.
3. Intersection (Region Y): Both forces have the ability to act at a distance; however, their mechanisms differ (mass vs. charge).

Therefore, the note about infinite reach, which applies to both forces, should be placed in the intersection (region Y).
