Question

A positively charged body has a deficiency of _____________
A) Electrons
B) Protons
C) Neutrons
D) Holes

Answer 1

Hint: Protons are positively charged species whereas electrons are negatively charged species. The total charge carried by the body depends upon the net difference in the protons and the electrons in the body.

Complete answer:
All bodies have electrons and protons in them which are the primary charge carriers of the body. Protons are positively charged species while electrons are negatively charged species. The total magnitude and kind of charge carried by a body depends upon the net difference in the number of protons and electrons in the body.
If a number has greater electrons than protons, then the body will be negatively charged. On the other hand, if the body has an excess of protons, it will be positively charged. A neutral body has the same amount of electrons and protons.
Therefore, for a positively charged body, there will be an excess of protons in comparison to electrons or it can also be said that the body has a deficiency of electrons with respect to the number of protons.

So, the correct answer is “Option A”.

Note:
Students must remember that protons are contained within the nucleus of an atom and are not free to move. On the other hand, electrons can be transferred from one body to another. Thus, when a body gets positively charged, it does not actually gain extra protons from its surroundings but it loses some electrons to the surroundings. This causes a net deficiency of electrons with respect to protons in the body and renders the body a net positive charge. Similarly, when a body gets negatively charged, it gains electrons from its surroundings.
