MCQ
Gold-leaf electroscope can be used _______?
- AOnly to detect the presence of charge.
- BTo detect the presence of charge as well as its nature (positive or negative).
- CTo measure the surface charge density.
- DTo measure current.

Answer
- To detect the presence of charge as well as its nature (positive or negative).
Explanation:
If the apparatus is initially in contact with some positively charged body and then comes in contact with another charged body and if the divergence increases we can deduce that the second body is also positively charged. If the divergence decreases then the second body must be negatively charged.
