Question

At a place of latitude 5°, angle of dip is nearly

विकल्प

• 10°

• 5°

• 20°

• 7.5°

Answer 1

7.5°

Explanation:

The angle of dip, also known as the magnetic dip, is the angle formed by the earth's magnetic field lines and the horizontal axis.

⇒ tan θ ≃ 2 tan δ

We can say for small latitudes that

θ ≃ 2 δ

∴ θ = 2 × 50 = 100
