The metal sphere of a small Van de Graaff generator illus- trated in Figure 15.23 has a radius of 18 cm. When the electric field at the surface of the sphere reaches 3.0 x 10° V/m, the air breaks down, and the generator discharges. What is the maximum potential the sphere can have before breakdown occurs?
