प्रश्न
A metal rod A is to be charged positively by using another charged rod B. What should be the kind of charge on the rod B if charging is to be done by conduction?

उत्तर
Rod A is uncharged and Rod B is charged body.
A is to be charged positively by touching i.e. by conduction. So rod / B should have a similar charge as is required by A i. e. +vely.
So rod B should be positively charged,
∴ By conduction same kind of charge is produced and shared by uncharged body.
