Question

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

• A. ${30}^0$
• B. ${75}^0$
• C. ${60}^0$
• D. ${45}^0$

Answer 1

The correct option is D ${45}^0$

$tan\delta =\frac{B_V}{B_H}=\frac{B_H}{B_H}=1$
$\therefore \delta ={45}^0$
