Charge A and charge B are 2.00 m apart, and charge A is +3.90 C and charge B is +4.00 C. Charge C is located between them at a certain point and the force on charge C is zero. How far from charge A is charge C?
Find the place where the forces due to A and B are equal and opposite. It will be closer to A than B.
