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.

Question 5:

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.

Solution:

When a glass rod is rubbed with a silk cloth, both bodies get equal charge with opposite nature. Equal amount of charge with opposite nature will cancel out each other. Hence sum of charge is equal to 0. 

hence when a glass rod is rubbed with a silk cloth ,the activity follow the law of conservation of charge.

Same phenomenon will observed with many other pairs of bodies
