Charging a gold-leaf electroscope by induction involves the following steps: 1. Bringing a charged object (in this case, a negatively charged ebonite rod) close to the cap of the electroscope. This causes the electrons in the cap to be repelled and move to the leaves, which causes them to separate. 2. Earthing the cap. This involves touching the cap of the electroscope with a finger or a conducting wire, which allows the excess charge to flow to the ground. This leaves the electroscope with a temporary charge imbalance. 3. Disconnecting the earthing. This involves removing the finger or conducting wire from the cap of the electroscope, which breaks the connection to the ground. 4. Removing the charged object (the negatively charged ebonite rod). Therefore, the correct sequence of steps for charging a gold-leaf electroscope by induction is: II (bringing a negatively charged ebonite rod close to the cap), III (earthing the cap), IV (disconnecting the earthing), and I (removing the ebonite rod). The answer is option (II, III, IV and I).
