The leaves of a positively charged electroscope diverge more when an object is brought near the knob of the electroscope. The object must be
Correct answer: C. positively charged
- A. an insulator
- B. negatively charged
- C. positively charged
- D. a conductor
Explanation
As, opposite charges repel leaves of a positively charged electroscope diverge when a positively charged object is brought closer.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
