Which of the following is not a unit of electric field intensity?
A $\frac{\mathrm{V}}{\mathrm{m}}$
B $\frac{N}{C}$
c $\frac{\text { dyne }}{\text { statcoulomb }}$
D None of these

Correct option is D None of these
$$
\begin{array}{l}
\mathrm{F}=\mathrm{q} \mathrm{E} \\
\mathrm{E}=\frac{\mathrm{F}}{\mathrm{q}}=\frac{\mathrm{N}}{\text { Coulomb }}=\mathrm{NC}^{-1}=\text { SI unit. }
\end{array}
$$
In CGS system of units, $E=\frac{\text { dyne }}{\text { stat Coulomb }}$
$\mathrm{Also}, \mathrm{E}=\frac{-\mathrm{dV}}{\mathrm{dr}}=\frac{\mathrm{V}}{\mathrm{m}}$
So, all of These are units of electric field intensity.

At a certain location in Africa, a compass points $12^{\circ}$ west of the geographic north. The north tip of the magnetic needle of a dip circle placed in the plane of magnetic meridian points above the horizontal. The horizontal component of the earth’s field is measured to be $0.16 \mathrm{G} .$ Specify the direction and magnitude of the earth’s field at the location.At a certain location in Africa, a compass points $12^{\circ}$ west of the geographic north.
