An isolated 7.0 cm radius spherical conductor has a total charge of 28 nC. It is connected to another conducting sphere with a radius of 5.0 cm, initially discharged, by means of a long conducting wire. After a sufficient period of time for the charges to be distributed on the two conductors, what is the charge (in nC) that the second sphere will have?
