The electric potential at a distance $r$ from a point charge $q$ is given by $V = kq/r$ , where $k = 9.0 \times 10^9\ \text{N·m}^2/\text{C}^2$ . What are the SI units of electric potential?

Volts (V) = joules per coulomb (J/C)

Newtons per coulomb (N/C)

Coulombs per meter (C/m)

Joules per meter (J/m)
