Answer 2

Answer:

In a Van de Graaff type generator a spherical metal shell is to be a 15×106V electrode. The dielectric strength of the gas surrounding the electrode is 5×107Vm−1.What is the minimum radius of thespherical shell required? (You will learn from this exercise why one cannot build an electrostatic generator using a very small shell which requires a small charge to acquire a high potential.)
