A positively charged rod is brought near the disc of a positively charged gold leafelectroscope. State your observation with reason

When a positively charged rod is brought near the disc of a positively charged gold leaf electroscope, the following observations are made:

1. Movement of Gold Leaves: The gold leaves of the electroscope will diverge (i.e., they will move apart from each other).

2. Reason for the Observation: This behavior can be understood through the principles of electrostatics. Both the rod and the electroscope disc are positively charged. Like charges repel each other, which means the positive charge in the rod will repel the positive charge in the electroscope. As the rod approaches, it causes further repulsion of electrons within the electroscope, leading to an increase in the positive charge at the top of the electroscope. Consequently, the leaves, which are also positively charged, experience repulsion and move apart.

This observation reinforces the principle that like charges repel, while unlike charges attract, resulting in the observable divergence of the gold leaves when subjected to a nearby positively charged object.
