Two point charges +2C and +6C repel each other with a force of 12N. If a charge of -2C is given to each of these charges, the force will now be:
Correct answer: A. Zero
- A. Zero
- B. 8N (repulsive)
- C. 8N (attractive)
- D. 16N (attractive)
Explanation
The initial force F is proportional to (2)(6) = 12. After adding -2C, the new charges are 0C and +4C. Since one charge is zero, the force between them will be zero.

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.
