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.
