Question

A positively charged sphere is connected to the earth

• A. The electrons from the earth flow into the sphere till it is electrically neutral.
• B. The electrons from the earth flow into the sphere till it gets negatively charged.
• C. The positive charges( protons) on the sphere flow into the earth.
• D. None of the above.

Answer 1

The correct option is A

The electrons from the earth flow into the sphere till it is electrically neutral.

1. Earth is considered a conductor of zero potential.
2. When a body is connected with the earth, this process is called earthing. The charge flows until the potential becomes equal.
3. Therefore, when the positively charged sphere is connected with the earth. The electrons start flowing from the earth to a spherical conductor.

Hence, option A is correct.
