Question 8 of 10According to Coulomb's law, what will happen to the electric force between two identical negative charges as they move closer together?A.Fe will stay negative and increase in magnitude.B.Fe will stay positive and increase in magnitude.C.Fe will become positive and decrease in magnitude.D.Fe will become negative and decrease in magnitude.
Solution
According to Coulomb's law, the electric force (Fe) between two charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
Given that the charges are identical and negative, the force between them will be repulsive (since like charges repel). This is represented by a positive Fe.
As they move closer together, the distance between them decreases. According to Coulomb's law, as the distance decreases, the force increases.
Therefore, the correct answer is:
B. Fe will stay positive and increase in magnitude.
