When a charged object induces a charge on another uncharged object without actually coming in contact with it, the process is termed as charging by induction. The charges developed on the uncharged body are known as induced charges.

When the balloon is rubbed on the student鈥檚 hair, it gets charged due to rubbing. When this charged balloon is brought near the water drip, the charges get induced in the water stream. Consequently, the charges of the water that has a polarity opposite to that on the balloon start moving to the face of the water stream, which is closer to the balloon due to the electrostatic force of attraction between the charges.

The charges that are accumulated on the closer face of the water stream cannot move out of it. As a result of the accumulation of charges of opposite polarity on the closer face of the water stream, it gets attracted toward the balloon. It thus follows a curved path instead of falling vertically.
