Question

define one coulomb charge?

Answer 1

The coulomb (symbolized C) is the standard unit of electric charge in the International System of Units (SI). ... The unit electric charge is the amount of charge contained in a single electron. Thus, 6.24 x 1018 electrons have 1 C of charge.

Answer 2

Answer:

One coulomb is that charge which repels an equal and similar charge with a force of 9 x 10⁹ N, when placed in vacuum at a distance of one metre from it.

Explanation:

The force is repulsive, if the charges are alike and attractive in case of unlike charges. Further, the electrostatic force between two charges is central in nature.

It may be pointed out that coulomb's law in electrostatics holds for stationary charges. Further, the two charges should be points in size.
