Question

A body can be negatively charged by

• A. Giving excess of electrons to it
• B. Removing some electrons from it
• C. Giving some protons to it
• D. Removing some neutrons from it

Answer 1

The correct option is A

Giving excess of electrons to it

Charge

1. The charge is the property of the body.
2. Although an electric charge cannot be formed or destroyed, it can be transported from one portion of a substance or system to another.
3. As a result, in an isolated system, the total charge remains constant.
4. Losing excess electrons leads to a positive charge.

Transfer of electrons and protons

1. When items rub against one other, they produce an electric charge that is either positive or negative.
2. Consider the scale and a piece of paper. When scales are smeared on hair and held close to a sheet of paper, the paper is drawn to the scale. It implies that they are both charged in some way.
3. When two substances are rubbed together, we know that some electrons from the atoms on the surface of one are removed and transferred to the other.
4. Negatively charged is the body that gets electrons, whereas positively charged is the body that loses electrons.
5. So, in general, there are two kinds of electric charges: positive and negative.
6. If an object gains or gives excess electrons, it is negatively charged; otherwise, it is positively charged if it loses excess electrons.

Hence, option A is the correct answer.
