2Take a glass rod and rub it with silk. Suspend it freely by a silk thread. Take an ebonite rod and rub it with cat’s skin. Observe that the glass rod is attracted by the ebonite rod. Observe that the suspended charged rod shows attraction.
The charge produced on the glass rod is called positive charge; whereas the charge produced on the ebonite rod is called negative charge. Hence there are two kinds of electric charges namely positive and negative
