How can extra charge be taken away from an object safely?
ABy painting it with an insulator
BBy earthing it with a conductor
CBy cooling it with cold water
DBy wrapping it in dry paper
Answer & Solution
Correct answer: B. By earthing it with a conductor
1. Earthing means joining the charged object to the ground with a conductor.
2. The extra electrons travel along that conductor into the ground.
3. The ground is so large that the extra charge has no overall effect there.
4. An insulator would trap the charge rather than let it escape.
