Question

The physical quantity having SI unit NC^–1m is ______.

Answer 1

The physical quantity having SI unit NC^–1m is electric potential.

Explanation:

The unit NC⁻¹ m means newton per coulomb multiplied by metre. Since NC⁻¹ is the unit of electric field (E), multiplying it by distance (m) gives electric potential. Hence, NC⁻¹ m = volt (V, which is the SI unit of electric potential.
