The vertical component of the earth's magnetic field is $\displaystyle 6 \times 10^{-5} \mathrm{~T}$ at any place where the angle of dip is $\displaystyle 37^{\circ}$. The earth's resultant magnetic field at that place will be (Given $\displaystyle \tan 37^{\circ}=\frac{3}{4}$ )
Official answer
(4)
$\displaystyle 1 \times 10^{-4} \mathrm{~T}$
