Answer
Construction
$1.$ Brass rod which passes through an insulator stopper in a glass case.
$2.$ Brass disc is at the top end of brass rod.
$3.$ Gold leaves Lower end carries two gold $($or aluminium$)$ leave held parallel when uncharged.
$4.$ Glass case protects the gold leaves from the outside air current.
$5.$ Metal foil present at the lower part of the glass case. This is connected to the earth when the electroscope is used.
