Well, self-energy is potential energy of unbalanced charge system (in this case the sphere had just charged and not in equilibrium state). Your answer: Ws = 1/(4pi*epsilon0)*3/5*p(r)*V/R. You could start from general definition formula of Ws = 1/2*q*V, then calculate for 3 case: r < R, r...

:rolleyes:I am designing temperature varying tube for VSM, especially high temperature. I don't have any experience on materials for this component. Please give me your idea about choosing material. Requirements for the tube is :shy:: - easy for machining - to use for medium vacuum (10^-4...
