How will you use a gold leaf electroscope to find out whether a body is charged or uncharged?
To test if the body is CHARGED OR UNCHARGED with GOLD LEAF ELECTROSCOPE: The body to be tested for charged or not is brought near the disc of Gold Leaf Electroscope and touched with the disc. If the leaves diverge, the body is charged and if leaves do not diverge, it is uncharged.
