The angle of dip at a certain place where the horizontal and vertical components of the earth's magnetic field are equal is

Options

  1. A30∘30^{\circ}
  2. B75∘75^{\circ}
  3. C60∘60^{\circ}
  4. D45∘45^{\circ}

Correct answer

D. 45∘45^{\circ}

Step-by-step solution

 Since BH=BV (Given) tan⁡δ=BVBH=BHBH=1∴δ=45∘\begin{aligned} & \text{ Since } B_H=B_V \text{ (Given) } \\ & \tan \delta=\frac{B_V}{B_H}=\frac{B_H}{B_H}=1 \\ & \therefore \quad \delta=45^{\circ}\end{aligned}
