Question 1
What does Coulomb’s Law state regarding two point charges?
- They repel each other
- The force is proportional to the distance between them
- The force is proportional to the product of their charges
💡 Hint: Remember the formula F = k * (q₁ * q₂) / r².
Question 2
True or False: Coulomb's Law only applies to like charges.
- True
- False
💡 Hint: Think about attraction and repulsion.

Challenge Problems
Push your limits with challenges.
Question 1
Two point charges of +5 µC and +3 µC are placed 0.4m apart. Calculate the force they exert on each other.
💡 Hint: Apply Coulomb's Law.
Question 2
If the distance between two charges is reduced to half, discuss the changes in the force experienced. Calculate it for charges of -2 µC and +4 µC at the new distance.
💡 Hint: Consider both the nature of distance and attraction/repulsion.
