Question

An uncharged electroscope can tell the nature of charge on a charged body. True/False.

Answer 1

A electroscope can be charged positively or negatively by touching the disc or the brass cap of the electroscope with a positively charged glass rod or negatively charged ebonite rod.
Only when the electroscope is charged, will the leaves collapse or diverge depending on the charge of the body for which the type of charge is to be determined.
Hence, the statement is false.
