Q. The value of angle of dip is zero at the magnetic equator because on it
A) $V\ and\ H$ are equal
B) The value of $V\ and\ H$ is zero
C) The value of $V\ is\ $zero
D) The value of $H\ is\ $zero
Explanation
(c) At magnetic equator, $V = 0$
$\therefore tan\phi = \frac{V}{H} = 0$
$\therefore\delta = 0$
