Question

Explain the angle of declination and angle of dip .prove that tan theeta = V/H​

Answer 1

Answer:

Note that tanθ=

H

V

...(1)

where θ is true value of dip . Here we assumed θ=∝

Now, angle of dips, θ

1

and θ

2

have different formula

tanθ

1

=

H×cos∝

V

...(2)

tanθ

2

=

H×sin∝

V

...(3)

From eqn (1), (2), (3), we can find value of H/V

which cotθ, which when calculate comes option B
