    Answer:

    Here ball and rod will repel each other as they are of similar charges

    Explanation:

    As we know that the two charges attract or repel each other by electrostatic force

    This force is given as

    F = \frac{kq_1q_2}{r^2}

    so we know if two charges are similar in nature then they will repel each other and if the two charges are opposite in nature then they will attract each other

    So here when rod touch the ball then it transfer its charge to the ball and due to similar charges in ball and rod they both repel each other
