Two objects are held close together. when they are released, they move toward one another. which conclusion is supported by this evidence? the objects are both positively charged. the objects are both negatively charged. the objects have no charge. the objects have opposite charges.

Option (d) is the correct answer.

Explanation:

It is known that objects which have opposite charges attract each other whereas objects which have like charges repel each other.

Therefore, when two objects are held close together and when they are released, they move toward one another then it means they have force of attraction between then.

This force of attraction can only arise if the objects are oppositely charged.

Thus, we can conclude that the objects have opposite charges.
