Sphere 1 has a charge 10μC and sphere 2 has charge 20 μC. The force that sphere 1 exerts on sphere 2 is 4.5 N. What is the magnitude of the force in Newtons that sphere 2 exerts on sphere 1?
To determine how the electrostatic force between two charged conducting spheres depends on the charge on the spheres. Electrostatic force between two charges is (a) directly proportional to the magnitude of the product the two charges and (b) inversely proportional to the square of the distance between their centers.
