If two charges are increased by two times then force_____________?
Correct answer: C. Increases 4 times
- A. Decreases 9 times
- B. Increases 9 times
- C. Increases 4 times
- D. Decreases 4 times
Explanation
From Coulomb’s law, force is proportional to the product of the two charges, F ∝ q₁q₂. Doubling both charges multiplies that product by 2 × 2 = 4.
