Two small aluminum spheres, each having mass 2.65×10−2 , are separated by 85.0 .

How many electrons would have to be removed from one sphere and added to the other to cause an attractive force between the spheres of magnitude 4.00×104 (roughly four ton)? Assume that the spheres may be treated as point charges.
