Question

two balls are placed near one another and hang down, as shown below. which conclusion is supported by this evidence? neither ball has a charge. the balls are both positively charged. one ball is positively charged, and the other is negatively charged. each ball has a charge, but the type of charge is unknown.

Explanation:

Charged objects can attract or repel each other. If the balls were charged and of the same sign (both positive or both negative), they would repel and move apart. If they were of opposite signs, they would attract and move towards each other. Since they are hanging down without any interaction, it means there is no electrostatic force between them, so neither ball has a charge.

Answer:

Neither ball has a charge.
