Question

1. A process which is used to protect electrical shocks due to leakage of electric current from any electric appliance
2. Why do two bodies get charged by rubbing against each other

Answer 1

Answer:

1 earthing

2.transfer of charges

Explanation:

1. as it is the property of charges to flow from higher potential to lower so they flow underground this is called earthing
2. due to rubbing the electrons get tranfered from one body to other. one body loses electron the other gains it thus developing static electricity.

Answer 2

Answer:

1) Earthing

Explanation:

2)When the two bodies are rubbed one body loses some electrons(only a negligible amount) and the other bodies gains this electrons,therefore the body that loses electrons becomes positively charged and the one that gains it becomes negatively charged.
