Answer 2

Answer:

The value of the vertical component of Earth's magnetic field and the value of the resultant field at that point are 0.20×10⁻⁴ T and 0.40×10⁻⁴ T respectively.

Explanation:

The vertical component of the earth's magnetic field is calculated as,

$\mathrm{B_v=B \times sin\delta}$                (1)

Where,

$\mathrm{B_v}$= vertical component of magnetic field

B= total magnetic field over an area ( it remains constant over an area)

δ=angle of dip

From the question we have,

The earths magnetic field is(B)=0.40 G=0.40×10⁻⁴Tesla

The angle of dip(δ)=30°

By inserting the value of "δ" and "B" in equation (1) we get;

$\mathrm{B_v=0.40\times 10^{-4} \times sin30\textdegree}$

$\mathrm{B_v=0.40\times 10^{-4} \times \frac{1}{2} }$

$\mathrm{B_v=0.20\times 10^{-4}\ T }$

So, the value of the vertical component of Earth's magnetic field and the value of the resultant field at that point are 0.20×10⁻⁴ T and 0.40×10⁻⁴ T respectively.
