Grounding a Negatively Charged Electroscope
While the negatively charged electroscope is touched and its charge becomes grounded or neutralized this is depicted within the animation below. The grounding procedure includes a transfer of electrons among the charged electroscope and the conducting object to that it is touched. While a negatively charged electroscope is touched electrons leave the electroscope to the ground. Since electrons repel another electron, their tendency is to spread out as far as possible by any conductor.
Properties of Lines of Flux To make the imaginary lines of flux describe the behaviour of the magnetic field we must give them appropriate properties. Thus lines of flux have
Five coulombs of charge are placed on a thin-walled conducting shell. Once the charge has come to rest, the electric potential inside the hollow conducting shell is found to be:
