Sphere 1 has a radius of R and an initial charge 2Q while sphere 2 has a radius of 3 R and an initial charge 8Q. A very thin copper wire is now connected to the spheres. Charge flows between the spheres until they reach the same electrical potential . How much charge will be transferred from sphere 2 to sphere 1? (Note that the charge transferred can be positive, negative or zero .) (1) Q/2 (2) 2Q (3) Q/3 (4) -3Q (5) None of these A Formula sheet...
