At a certain place, the angle of dip is $60 °$ and the horizontal component of the earth's magnetic field $(B_{H})$ is $0 .8 \times 10^{- 4} T .$ The earth's overall magnetic field is

Options:

Answer:

Solution:

Given,

$B_{H} = 0.8 \times 10^{- 4} T$

$θ = 60^{o}$

$B_{e} = ?$

We know that,

$B_{H} = B_{e} \cos θ$

$0.8 \times 10^{- 4} = B_{e} \cos 60^{o}$

$B_{e} = \frac{0.8 \times 10^{- 4}}{\frac{1}{2}}$

$= 1 .6 \times 10^{- 4} T$
