Question

The aluminium strips in an electroscope as shown in fig. 15.1 are replaced by plastic strips and a charged body is brought in contact with the metal clip. What will happen?

Answer 1

If the metal clip used in the electroscope is replaced by an ebonite rod and a charged body is brought in contact with it, therefore, there will be no charge on the aluminium strips and no repulsion of the strips will occur.
