Challenge Problems
Push your limits with advanced challenges
A positively charged rod repels a light object with a charge of +2µC. If the rod has a charge of +8µC, calculate the forces at play if they are 10cm apart.
💡 Hint: Use k ≈ 9 x 10^9 N m^2/C^2.
Two charged spheres A (+3µC) and B (-3µC) are placed 30cm apart. How will the force acting on them change when both are replaced by spheres of charge +5µC and -5µC?
💡 Hint: Analyze how the additional charge affects the force.
