Question

The SI unit of electric dipole moment is:

विकल्प

• Newton per Coulomb (N/C)

• Coulomb per metre (C/m)

• Coulomb-metre (C·m)

• Joule per metre (J/m)

Answer 1

The electric dipole moment, defined as the product of charge (in Coulombs) and distance (in metres), has the SI unit of Coulomb-metre (C·m). This unit directly reflects the dimensional combination \[M^0L^1T^1A^1\], where charge contributes the ampere-second dimension.
