1. Electric Charges and Fields
hard
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
Solution
(b) 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.
