उत्तर
Aim - To show that there are two kinds of charges.
Apparatus - gold-leaf electroscope, glass rod rubbed with a silk cloth.
any two non-identical bodies say A and B.
Procedure -
- Charge the gold leaf electroscope positively by touching it with glass rod rubbed with a silk cloth.
- The gold leaf electroscope shows its charging by showing its leaves diverging.
- Touch the brass cap of this electroscope with body A-Note the divergence of the gold leaves.
- Now touch the brass cap with body Band note the divergence.
Observation
In the case of body A - Leaves further diverge.
In the case of body B - leaves converge.
Inference - Body A (positively charged)
Body B (negatively charged)
So there are two types of charges.
