Question

Which units are used instead of one coulomb for practical use in electrostatics?

पर्याय

• \[1\,\mathrm{kg}\] or \[1\,\mathrm{g}\]

• \[1\,\mathrm{mC}\] or \[1\,\mu\mathrm{C}\]

• \[1\,\mathrm{N}\] or \[1\,\mathrm{J}\]

• \[1\,\mathrm{m}\] or \[1\,\mathrm{km}\]

Answer 1

One coulomb is too large a unit for practical use. Smaller units such as \[1\,\mathrm{mC}\] or \[1\,\mu\mathrm{C}\] are used in electrostatics.
