A charged body is brought near a positively charged gold leaf electroscopes. The divergence of its leaves increases.What is the kind of charge on the body?
- A. Positive
- B. Negative
- C. Neutral
- D. Data insufficient
Step-by-step solution
The positively charged electroscope's leaves diverge due to repulsion of like charges. When a positively charged body is brought near, it repels more positive charge to the leaves via induction, increasing the net positive charge on the leaves, thus increasing divergence. A negative charge would attract positive charge to the cap, reducing leaf charge and divergence. Neutral has no effect.
