Electrostatics Question 189

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 [AMU 1995]

Options:

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

Show Answer

Answer:

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.
