When an ebonite rod is rubbed on fur some of the electrons are transferred from the fur to the ebonite. Therefore the ebonite becomes negatively charged while fur transferred from the fur to the ebonite. Therefore the ebonite becomes negatively charged while fur becomes positively charged. While when the glass rod is rubbed in silk electron will be transferred from glass rod to silk, the glass rod will be positively charged while silk will be negatively charged. 2. BY CONTACT This is the method of charging the body by touching each other. Let’s say x is positively charged and y is negatively charged. Then the positive charge will be transferred to body y, and then after sometime they will repel each other since they will have equal charge. 3. BY INDUCTION This is the method of charging the body without touching. Let body x be negatively charged while body y lies both positive and negative.
