    What happens when an ebonite rod rubbed with fur and a glass rod rubbed with silk are brought near each other?

    A)  They attract each other.

    B)                         They repel each other.

    C)                         Nothing happens to them.

    D)                         They acquire heat.

    Correct Answer: A

    Solution :

    The charge on the ebonite rod rubbed with fur is negative (as it gains electrons). The charge on the glass rod rubbed with silk is positive (as it loses electrons). So, when these two rods are brought close to each other, they attract, since unlike charges attract each other.
