The angles of dip at two places are 30° and 45°. The ratio of horizontal components of earth’s magnetic field at the … √2 (c) 1…
Answers:
The correct option (a) √3 : √2
Explanation:
δ1 = 30°
δ2 = 45°
Horizontal component of earth’s magnetic field,H1 = B cosδ1
H2 = B cosδ2
∴ (H1/H2) = [(cosδ1)/(cosδ2)]
= [(cos 30)/(cos 45)]
= [(√3/2)/(1/√2)]
= (√3/2) × √2 = √(3/2)
