At place on earth, the vertical component of earth’s magnetic field is √3 times its horizontal component. The angle of dip at this place is …….
Options
(a) 60⁰
(b) 30⁰
(c) 45⁰
(d) 0⁰
Correct Answer:
60⁰
Explanation:
As vertical component of Earth’s magnetic field is Bᵥ = √3 Bʜ
Angle of dip at any place is a given by, tan δ = Bᵥ / Bʜ = Bᵥ = √3 Bʜ / Bʜ = √3
Then, δ = tan⁻¹ (√3) = 60⁰
