Answer Details
When a positively charged glass rod is brought near the cap of a positively charged electroscope, the charge on the electroscope cap is repelled by the charged glass rod. As a result, the cap loses some of its charge and the electrons move down to the leaves, causing them to acquire a positive charge. The like charges on the leaves cause them to repel each other, causing them to diverge. Therefore, the divergence of the leaf will increase. Thus, the correct option is (b) increase.
