Question: A Van de Graff generator has a dome 56 cm in diameter. The maximum field that the air can withstand is 3.0 x 106 V/m.
Part A: Calculate the maximum electric potential it can reach before the surrounding air breaks down because of the electric field near the surface of the dome.
Please show me how you solve the above question.
