If we double the separation between two charges , then coulomb's force will become?
Correct answer: D. 1/4th
- A. Double
- B. Half
- C. Four times
- D. 1/4th
Explanation
Coulomb's law states that the force between two point charges is directly proportional to the product of the magnitudes of charges and inverselyproportional to the square of the distance between them. So, if the separation is doubled the force becomes 1/4 of the original force.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
