The horizontal component of earth’s magnetic field at a place is 0.2 G, whereas its total magnetic field is 0.4 G. The angle of dip at the place is
Horizontal component BH = B cosδ.
Given: BH 0.2G, B = 0.4G
So, cosδ = 0.2/0.4 = 0.5
δ = cos⁻¹ (0.5) = 60°.
Answer: (C) 60°.

The angle of dip
θ is given by:
cos
θ =
B
H/
B
Where
B
H
=0.2G (horizontal component) and
B = 0.4G (total field).
cosθ = 0.2/0.4 = 0.5 ⇒ θ = cos⁻¹
(0.5) = 60°
Answer: (C) 60°.
