Question: If two identical charges are placed 1 meter apart, what happens to the force between them if the distance is doubled?

Options:

Correct Answer: It halves

Solution:

According to Coulomb\'s law, force is inversely proportional to the square of the distance. If the distance is doubled, the force becomes one-fourth.

If two identical charges are placed 1 meter apart, what happens to the force between them if the distance is doubled?

Correct Answer: Force becomes one-fourth.

Step 1: Understand that we have two identical charges placed 1 meter apart.
Step 2: Recall Coulomb's law, which states that the force between two charges is inversely proportional to the square of the distance between them.
Step 3: If the distance is doubled from 1 meter to 2 meters, we need to calculate the new force.
Step 4: Since the distance is doubled, we square the new distance: (2 meters)² = 4.
Step 5: The force is now 1 divided by 4 (the square of the new distance), which means the force is reduced to one-fourth of the original force.

Coulomb's Law – Coulomb's law describes the electrostatic force between two charges, stating that the force is inversely proportional to the square of the distance between them.
