Question

When a positively charged glass rod is made to touch the metal knob of an electroscope, the leaves of the electroscope become _____ and ______.

• A. positively charged; attract each other
• B. negatively charged; attract each other
• C. negatively charged; repel each other
• D. positively charged; repel each other

Answer 1

The correct option is D positively charged; repel each other

When a positively charged body is brought near the metallic knob of a gold leaf electroscope and made to touch it, the leaves of the electroscope also become positively charged due to conduction.
And since like charges repel, the two gold leaves would repel each other.
