What will be the effect on the divergence of the leaves of a uncharged gold leaf
What will be the effect on the divergence of the leaves of a uncharged gold leaf electroscope on bringing a negatively charged rod near electroscope?
- A. Leaves diverge
- B. Leaves converge
- C. Leaves remains at same position
- D. Can not be determined
Step-by-step solution
When a negatively charged rod is brought near the cap of an uncharged gold leaf electroscope, electrons in the cap are repelled down to the leaves. This induces a positive charge on the leaves (due to electron deficiency) and a negative charge on the cap. The leaves, now both positively charged, repel each other and diverge.
