Choose the correct option.

Choose the correct option.Choose the correct option.

Options

  1. ATrue dip is not mathematically related to apparent dip.
  2. BTrue dip is less than apparent dip.
  3. CTrue dip is always greater than the apparent dip.
  4. DTrue dip is always equal to apparent dip.

Correct answer

B. True dip is less than apparent dip.

Step-by-step solution

If the apparent dip circle is at an angle α\alpha with true dip circle then,

Choose the correct option.

tan⁡(ϕ′)>tan⁡(ϕ)⇒ϕ′>ϕ\tan \left(ϕ '\right) > \tan \left(ϕ\right) ⇒ ϕ ' > ϕ

Therefore, apparent dip angle is greater than true dip angle.

Hence, true dip (ϕ)( ϕ ) is less than apparent dip \left({ϕ}^{'}\right)$
