Lightning can be studied with a Van de Graaff generator, which consists of a spherical dome on which charge iscontinuously deposited by a moving belt. Charge can be added until the electric field at the surface of the dome becomesequal to the dielectric strength of air. Any more charge leaks off in sparks as shown in the figure below. Assume the domehas a diameter of 40.0 cm and is surrounded by dry air with a "breakdown" electric field of 3.00 x 10° V/m.(a) What is the maximum potential of the dome?3e5 XYour response differs significantly from the correct answer. Rework your solution from the beginning and checkeach step carefully. kV(b) What is the maximum charge on the dome?µC
