Question

A positively charged body has
A. an excess of photons
B. an excess of electrons
C. an excess of protons
D. a deficiency of protons

Answer 1

Hint: Photons are bundles of light (or light particles) they hold no charge. In an atom, electrons are negatively charged particles which move around a positively charged nucleus. Protons are positively charged particles that are present in the nucleus.

Complete step by step answer:
An atom is considered to be consisting of positively and negatively charged particles. Thus, we experience no charge frequently in our day to day life. But consider the phenomenon of static electricity. During winter time, if we even touch door knobs after sitting on a plastic chair, we experience electric shock. This happens because excess charge on our body tries to escape through the fingers to the ground. When we rub two uncharged bodies, one of them gets positively charged and another gets negatively charged. This is what happened between the chair and our body.
The charge designation of the body is usually done by the virtue of electron exchange. When electrons from one body enter another body, then the body with excess electrons is negatively charged and the body which lost its electrons becomes positively charged. Protons are considered to be present in the nucleus so they remain fixed.
Thus, compared with the number of electrons, a positively charged body (which has lost some of its electrons) has an excess of protons.

So, correct answer is option (C).

Note:
Specific bodies are able to exhibit static electricity phenomena. At least one of the two surfaces that are being rubbed should be an insulator. Noted examples for such pairs include: glass rod and silk, balloon and hair, ebonite rod and fur, etc.
