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.)
