If the vertical component of the earth's magnetic field is 0.45 G at a location, and angle of dip is \(60^{\circ}\), then magnetic field of earth in that location is
- A 0.26 G
- B 0.52 G
- C 0.3 G
- D 0.7 G
Answer & Solution
Correct Answer
(B) 0.52 G
Step-by-step Solution
Detailed explanation
\begin{aligned} & \mathrm{B}_{\mathrm{v}}=0.45 \mathrm{G}, \delta=60^{\circ} \\ & \therefore \quad \mathrm{B}_{\mathrm{v}}=\mathrm{b} \sin \delta \\ & \Rightarrow \mathrm{B}=\frac{\mathrm{B}_{\mathrm{v}}}{\sin \delta}=\frac{0.45}{\sin 60^{\circ}}=\frac{0.9}{\sqrt{3}}=0.52…
