A) halves.
B) increases, but we can't say how much without knowing the distance between them.
C) becomes zero.
D) doubles.
E) quadruples.

Quizplus · Accepted Answer

The force between two charged objects is given by Coulomb's law, which states that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. If the charges on both objects are doubled, the product of the charges becomes four times larger (since 2 * 2 = 4), and since the distance does not change, the force quadruples.
