Question

q4. an object is brought close to a metal leaf electroscope. draw the leaves within the electroscope showing that a strong positive charge was brought toward the sphere. explain your reasoning.

Explanation:

When a strong positive charge is brought near the metal leaf electroscope's sphere, electrostatic induction occurs:

1. The positive charge attracts free electrons in the electroscope's conductive material (sphere, rod, and leaves) toward the sphere, leaving the thin metal leaves with a net positive charge.
2. Since like charges repel each other, the two positively charged leaves will move apart (diverge from each other).

To draw this: Sketch the electroscope with the two thin leaves spread outward from their central rod, rather than hanging straight down.

Answer:

The metal leaves of the electroscope will diverge (spread apart). This happens because the nearby positive charge induces a net positive charge on both leaves via electrostatic induction, and like positive charges repel one another.
