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