A conducting shell of radius R has total charge Q. If sawed in half, the two halves
Question:
A conducting shell of radius R has total charge Q. If sawed in half, the two halves of the shell will fly apart. This can be prevented by placing a point charge Q' at the center of the shell.
(a) What value of Q' just barely holds the shell together?
(b) How does the answer to part (a) change for the case of an insulating sphere with uniform charge density σ = Q/4πR2?
