Question

Explain how, using a capacitor with gold leave electroscope, may increase the sensitivity of the electroscope

Answer 1

Indeed, using a capacitor with gold leave electroscope may increase the sensitivity of the electroscope. All we need is to charge the capacitor to some voltage with a battery cell, connect either plates of the capacitor to the electroscope, and the leaves will diverge at lower voltages.
