    A glass rod rubbed with silk is used to change a gold leaf electroscope and the leaves are observed to diverge. The electroscope thus charged is exposed to X-rays for a short r period. Then

    A) the divergence of leave will not affected

    B) the leaves will diverge further

    C) the leaves will collapse

    D) the leaves will melt

    Correct Answer: B

    Solution :

    Charge on glass rod is positive, so charge on gold leaves will also be positive. Due to X-rays more electrons from leaves will be emitted, so leaves becomes more positive and diverge further.
