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.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
