When a galss rod is rubbed with a sild cloth charges appear on both a smilar phenomenon is observeed with many other pairs of bodies expalin how this observation is consistent with the law of conservation of charge

Text Solution

Verified by Experts

Rubbingproduces 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 systen of two rubbed dodies is zero . This is because equal amount of opposite charge annihilate each other . When a glass rod is rubbed with a silk cloth , opposite natured charges appear on both the law of conservation of energy A similar phenomenon is observed with many other pairs of bodies.
