Which of the following is not a unit of electric field intensity? |
$N C^{-1}$ $N A^{-1} s^{-1}$ $V m^{-1}$ $V m$ |
$V m$ |
The correct answer is Option (4) → $V m$ Electric field intensity $E$ is defined as force per unit charge: $E = \frac{F}{q}$ Units: - $N/C = \text{Newton per Coulomb}$ - $V/m = \text{Volt per meter}$ - $V m = \text{Volt meter}$ → This is not a unit of electric field intensity - $N A^{-1} s^{-1}$ can be converted to $N/C$, so it is valid |
