Challenge Problems
Push your limits with advanced challenges
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.
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.
