Two small negatively charged spheres spaced 35.00 cm apart have equal amounts of net charge. If the magnitude of the force of repulsion between them is 2.430 x 1021 N, How many excess electrons must be present on each sphere? (For this calculation, use ke-8.988 x 109 Nm2/C2 for Coulomb's constant and use qo 1.602 x 10-19C for the charge of an electron).

Two isolated conducting spheres are separated by a large distance. Sphere 1 has a radius of 20 cm and an initial charge 30 nC while Sphere 2 has a radius of 60 cm and an initial charge 70 nC. A very thin copper wire is now connected to the spheres to allow charge to flow between them. How much charge will be transferred from Sphere 2 to Sphere 1? (Note that the charge transferred can be positive, negative or zero.)
