Q.At a particular place, the vertical component of earth's magnetic field is two times of its horizontal component. The angle of dip at that place is θ, then tan θ is

The angle of dip satisfies tan θ = (vertical component)/(horizontal component) = V/H. Given V = 2H, tan θ = 2. Option (a).

Step 1 — definition of dip: the vertical component V and horizontal component H of the Earth's magnetic field are related to the dip angle θ by tan θ = V/H (NCERT …

The angle of dip relates H and V by tan(dip) = V/H; substituting 60° gives H/V = 1/√3.

The angle of dip $\delta$ at a place is defined by:

$\tan\delta = \dfrac{V}{H}$

where $V$ and $H$ are the vertical and horizontal components of the Earth's magnetic field.
