If the metallic body of electroscope is earthed ,it measures potential in experiments. Without earthing the quantity measured by it is charge. This is related to potential difference by V=Q/C but is not same as the potential difference because there is a lot of variation in capacitance during an experiment.
a)When a positively charged body is brought near uncharged electroscope the leaves of electroscope will diverge.
b) When it is brought near a positively charged electroscope,the charge on the leaves becomes more positive and the leaves will diverge.
c) if a positively charged body is brought near to a negatively charged electroscope,the magnitude of charge on the leaves decreases and the leaves consequently move closer together
