Two small identically charged balls are a certain distance apart.The vectors in the figure show the magnitude and direction of the electrostatic force on each ball due to the other one.Suppose that the charge on the left ball is now doubled (represented by two plus signs).Which vector diagram below best represents the forces that are now exerted on each of the two balls?

Question

Quizplus · Accepted Answer

When the charge on the left ball is doubled, the electrostatic force on each ball will also double according to Coulomb's law. This means that both vectors will double in magnitude but will still point in the same direction as before. Choice C accurately represents this scenario with both vectors doubling in magnitude and maintaining the same directions as before.
