प्रश्न
If the metal clip used in the electroscope is replaced by an ebonite rod and a charged body is brought in contact with it, will there be any effect on the aluminium strips? Explain.
उत्तर
No, there will not be any repulsion between the aluminium strips. The charged body will not transfer any type of charge to the ebonite rod as ebonite rod is an insulator. Therefore, there will be no charge on the aluminium strips and no repulsion of the strips will occur.
