Q. The correct relation is [Where $B_{H} =$ Horizontal component of earth’s magnetic field; $B_{V} =$ Vertical component of earth’s magnetic field and $B =$Total intensity of earth’s magnetic field]
A) $\mathbf{B} = \frac{B_{V}}{B_{H}}$
B) $\mathbf{B} = B_{V} \times B_{H}$
C) $\left| \mathbf{B} \right| = \sqrt{B_{H}^{2} + B_{V}^{2}}$
D) $\mathbf{B} = B_{H} + B_{V}$
Explanation
The correct answer is Option C: $\left| \mathbf{B} \right| = \sqrt{B_{H}^{2} + B_{V}^{2}}$.
