Question

If the inclination is θ, the horizontal component of the earth’s field is H_E and the vertical component of the earth’s field is Z_E, then tan(θ) is ______.

Options

• `"H"_"E"/"Z"_"E"`

• `"H"_"E"^2/"Z"_"E"^2`

• `"Z"_"E"^2/"H"_"E"^2`

• `"Z"_"E"/"H"_"E"`

Answer 1

If the inclination is θ, the horizontal component of the earth’s field is H_E and the vertical component of the earth’s field is Z_E, then tan(θ) is `underline("Z"_"E"/"H"_"E")`.

Explanation:

Z_E = B sin θ

H_E = B cos θ

Dividing the two we get, `tan theta = "Z"_"E"/"H"_"E"`.
