When a Glass Rod is Rubbed with a Silk Cloth, Charges Appear on Both. a Similar Phenomenon is Observed with Many Other Pairs of Bodies. Explain How this Observation is Consistent with the - Physics

Answer in Brief

When a glass rod is rubbed with a silk cloth, charges appear on both. A similar phenomenon is observed with many other pairs of bodies. Explain how this observation is consistent with the law of conservation of charge.



Rubbing produces charges of equal magnitude but of opposite nature on the two bodies because charges are created in pairs. This phenomenon of charging is called charging by friction. The net charge on the system of two rubbed bodies is zero. This is because equal amounts of opposite charges annihilate each other. When a glass rod is rubbed with a silk cloth, opposite-natured charges appear on both bodies. This phenomenon is consistent with the law of conservation of energy. A similar phenomenon is observed with many other pairs of bodies.
