On a large scale, matter is mostly neutral. What is true of electric forces on a large scale?

a) They are exactly zero.

b) They are mostly negative.

c) They are close to zero.

d) They are mostly positive.

Respuesta :

c) They are close to zero.

Answer: The correct option is (c).

Explanation:

The electric force exists between the charged particles only.

The electric force between the negatively or positively charged particles is attractive in nature while the electric force between the negative and the positive charged particles is repulsive in nature.

Matter consists of atoms. Atom consists of electrons, protons and neutrons. Only, electrons can move. If the atom loses electrons then matter gets negatively and positively charge respectively.

In the given problem, the matter is mostly neutral on a large scale. On a large scale, the electric forces are close to zero.

Therefore, the correct answer is (c).
