Question

If horizontal and vertical components of the earth's magnetic field are equal at a certain place, then the angle of the dip at that place will be

• A. ${90}^o$
• B. ${60}^o$
• C. ${45}^o$
• D. $0^o$

Answer 1

Answer: (C)

${45}^o$

$I\cos \theta =H$
$I\sin \theta =V$
$V=H$
$\therefore \tan \theta =1$
$\theta ={45}^o$
