Question 47: Magnetism and Matter

Question

At a certain place the angle of dip is 30$^\circ$ and the horizontal component of earth's magnetic field is 0.5 G. The earth's total magnetic field (in G), at that certain place, is :

Accepted Answer

${B_H} = B\cos 30^\circ $
$ \Rightarrow B = {1 \over {\sqrt 3 }}G$

Answer

${1 \over {\sqrt 3 }}$

Answer

${1 \over 2}$

Answer

$\sqrt 3 $
