Earth can be regarded as a large reservoir of oppositely charged particle, electrons and protons. Earth on a whole is electrically neutral. By any means , if we take out or add some electrons to the earth. its charge will remain almost zero.Thus the earth is regarded as large capacitor with zero potential under all practical conditions. Any body connected to earth becomes its part and hence has zero potential.
Earthing: When a body comes in contact with the earth, either directly or indirectly, then the charges are discharged to the earth. This is called earthing. The process of transfer of charges from a charged object to the earth is called earthing or grounding.
When a positively charged body is connected to the earth, the electrons start flowing from the earth till the positive charge of the body becomes zero, and hence potential of the body V becomes zero.
When a negatively charged body is connected to earth, the electrons from the body start flowing to the earth, till the body becomes neutral and hence its potential becomes zero.
A negatively charged body is connected to the ground then choose the correct statement:

A marvelous experience with Abhyas. I am glad to share that my ward has achieved more than enough at the Ambala ABHYAS centre. Years have passed on and more and more he has gained. May the centre flourish and develop day by day by the grace of God.
My experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
My experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.
I have spent a wonderful time in Abhyas academy. It has made my reasoning more apt, English more stronger and Maths an interesting subject for me. It has given me a habbit of self studying
It has a great methodology. Students here can get analysis to their test quickly.We can learn easily through PPTs and the testing methods are good. We know that where we have to practice
One of the best institutes to develope a child interest in studies.Provides SST and English knowledge also unlike other institutes. Teachers are co operative and friendly online tests andPPT develope practical knowledge also.
My experience was very good with Abhyas academy. I am studying here from 6th class and I am satisfied by its results in my life. I improved a lot here ahead of school syllabus.
Being a parent, I saw my daughter improvement in her studies by seeing a good result in all day to day compititive exam TMO, NSO, IEO etc and as well as studies. I have got a fruitful result from my daughter.
It was a good experience with Abhyas Academy. I even faced problems in starting but slowly and steadily overcomed. Especially reasoning classes helped me a lot.
It was good as the experience because as we had come here we had been improved in a such envirnment created here.Extra is taught which is beneficial for future.
