Answer 2

,
As gold is malleable metal .Not only gold but also copper is also used here in electroscope .

A reason why these metals are used is that they are malleable more than any other metal. To use the electroscope, you need to put a thin trey into it.

Another reason is that Gold is less reactive. If you put a highly reactive metal as trey's substance, then that metal will react with the electrons that pass through it and will leave the observer a hard chance of having a good view.

This thin metal plates helps in the earthing of the charges that accumulate on the side walls of the electroscope .

Here is your answer

I hope my answer is help you
