the divergence of leave will not affected
the leaves will diverge further
the leaves will collapse
the leaves will melt
Validate
Solution:
As charge on glass rod is +(ve) so charge on gold leaves will also be +(ve). Due to X-rays more electrons from leaves will be emitted, so leaves becomes more positive and diverge further.
