Consider two isolated, charged conducting spheres. One is a large sphere, and the second is smaller with a radius four times smaller than that of the large sphere but with four times as much charge. We denote the potential of the large sphere by and the electric field at its surface by The corresponding quantities for the smaller sphere are (a) Compute the ratio EL /ES. (b) Find
