Question

At a certain place, the horizontal component of earth's magnetic field is $\sqrt{3}$ times the vertical component. The angle of dip at that place is

• A. ${30}^{}$
• B. ${60}^{}$
• C. ${45}^{}$
• D. ${90}^{}$

Answer 1

Answer: (A)

${30}^{}$

$\tan \theta =\frac{\text{Vertical component}}{\text{Horizontal component}}$

$\tan \theta =\frac{1}{\sqrt{3}}$

$\theta ={30}^{\circ }$

Hence option 'A' is correct.
