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

Question

A glass rod rubbed with silk is used to charge a gold leaf electroscope and the leaves are observed to diverge. The electroscope thus charged is exposed to X-rays for a short period. Then (A) the divergence of leaves will not be affected (B) the leaves will diverge further (C) the leaves will collapse (D) the leaves will melt

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.

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

the divergence of leaves will not be affected

the leaves will diverge further

the leaves will collapse

the leaves will melt

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.
