Answer
Suppose we want to charge a metal rod A negatively, proceed as follows:
- Place the rod A on insulating stand.
- Take a positively charged glass rod B provided with an insulating handle.
- Bring it near the rod A.
- The near end P of the metal rod A will acquire negative charge while the far end Q acquires positive charge as shown in below figure.
- Now touch the end Q of rod A by hand. Then remove hand and glass rod B simultaneously.
- The rod A becomes negatively charged.
