Question

A point near the equator has: ( H and V are horizontal and vertical components of Earth's magnetic field at a point) (A) H gg V (B) V=H ≠ 0 (C) V gg H (D) V=H=0

As tan δ=(V/H) At equator, δ=0, So, H gg V

Q. A point near the equator has: ( $H$ and $V$ are horizontal and vertical components of Earth's magnetic field at a point)

$H ≫ V$

$V = H \neq = 0$

$V ≫ H$

$V = H = 0$

As $t an δ = \frac{V}{H}$
At equator, $δ = 0,$
So, $H ≫ V$

Q. A point near the equator has: ( H and V are horizontal and vertical components of Earth's magnetic field at a point)

H≫V

V=H=0

V≫H

V=H=0
