Question

q3. determine the charge on the object brought near the sphere of the metal leaf electroscope by examining the images. draw the charge on the object.

Explanation:

Step1: Analyze initial electrostate

In the first image, the electroscope has induced charges (equal + and - on leaves, sphere) with no external object, so it's neutral initially, with leaves collapsed.

Step2: Observe leaf behavior with object

In the second image, the electroscope leaves repel (spread apart) and the sphere has net positive charge, while the leaves also have positive charge. This means the external object induced a movement of negative charges: negative charges in the electroscope are attracted to the object, leaving the sphere and leaves with net positive charge.

Step3: Deduce object charge

For negative charges in the electroscope to be attracted to the external object, the object must have a negative charge (opposite charges attract).

Answer:

The object brought near the electrosphere has a negative charge (all over its surface, drawn as $-$ symbols distributed on the light blue object).
