If you were to positively contact charge a small ~1 mm diameter sphere using a Van de Graaff generator, and were to charge it sufficiently high enough that field evaporation began to occur, what would happen?
Would the rate of evaporation increase exponentially as the field strength would increase with decreasing sphere radius? Or would the evaporated particles reduce the positive charge of the sphere enough to prevent further field evaporation?
Alternatively, what if you contact charged a small ~1 mm sphere to a voltage much higher than that at which significant field evaporation occurs. Would it explode?
