Mention various kinds of electrification

1-

There are two kinds of electrification. For example, when two light hard-rubber balls are electrified by silk strings will be observed to repel each other. But a glass ball rubber with silk will attract either of the rubber balls, although two such glass balls will repel each other. The charge on the glass is evidently unlike that on the rubber. These facts suggest the first law of electrostatics: Objects that are similarly change repel each other; bodies with unlike charges attract each other.
