Question

A positively charged body, when brought closer to a positively charged pith ball electroscope, would make the ball ______.

• A. move away from the body
• B. oscillate like a pendulum
• C. move toward the body
• D. become hot with time

Answer 1

The correct option is A move away from the body

A pith ball electroscope helps in identifying the presence and nature of electric charge present on an object. When a positively charged object is brought near a positively charged pith ball electroscope, as a natural reaction, the two repel each other. So, the pith ball moves away from the object.
