Answer Details
When a positively charged glass rod is placed near the cap of a positively charged electroscope, it will repel the positive charges in the electroscope, causing the charges to move away from the cap and towards the leaves. As a result, the leaves will experience a repulsive force and will diverge, indicating that the electroscope is charged.
If the glass rod is brought closer to the cap, the repulsive force will become stronger, causing the leaves to diverge further. Therefore, the divergence of the leaves will increase.
So the correct answer is "increase".
