A glass rod rubbed with silk is suspended near an ebonite rod rubbed with fur. What will be your observation? Give a reason to your answer.
Answer
When a glass rod rubbed with silk is suspended near an ebonite rod rubbed with fur, both the rods attract each other. The glass rod when rubbed with silk acquires positive charge as free electrons move from glass to silk. Similarly when an ebonite rod is rubbed with fur, it acquires negative charge as free electrons move from fur to rod. As the charges on the rods are opposite, hence they attract each other.
