What will be the charge:
a) on the metal cap
b) on the leaves of an electroscope, if you bring a positive rod near the end of its metal cap
- When a positive charged rod is brought near to the cap of gold leaf electroscope, then opposite charge is induced on the cap and similar charge is induced on the leaves.
- Hence, the charge on the metal cap is negative and the charge on the leaves of electroscope is positive.
