In a Van de Graff type generator a spherical metal shell is to be a 15xx10^6V electrode. The dielectric strength of the gas surrounding the electrode is 5xx10^7Vm^-1 . What is the minimum radius of the spherical shell required ? (You will learn from this excerise why one cannot build and electrostatic generator using a very small shell which requires a small charge to acquire a high potential. )

In a Van de Graaff type generator, a spherical metal shell is to be a 15 xx 10^6V electrode. The dielectric strength of the gas surrounding the electrode is 5 xx 10^7 Vm^(-1) . What is the minimum radius of the spherical 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.)
