Two point charges are separated by a distance of 4m. The force between them is 4N. What is the force between the charges when the distance between them is 1m
Correct answer: A. 16 N
- A. 16 N
- B. 1 N
- C. 64 N
- D. 32 N
Explanation
According to Coulomb's law( F = k * (|q₁| * |q₂|) / d²), the force between two charges is inversely proportional to the square of the distance between them. Therefore, if the distance is reduced to 1/4 of its original value (from 4m to 1m), the force between them increases by 4^2=16 times.Incorrect options: (b), (c), (d) These options don't accurately represent the relationship between force and distance according to Coulomb's law.

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.
