Expert Answer
When a negatively charged body is brought near the cap of a gold leaf electroscope whose case is earthed,then the electrons near the brass disc of the electroscope gets repelled and so they move from the brass disc to the leaves .As a result the positive charge on the leaves gets reduced and hence the leaf has an induced negative charge.
