The angle of dip at equator is
- A \(\frac{\pi}{2}\)
- B \(\frac{\pi}{3}\)
- C \(\frac{\pi}{4}\)
- D zero
Answer & Solution
Correct Answer
(D) zero
Step-by-step Solution
Detailed explanation
The angle of dip is the angle that the Earth's total magnetic field makes with the horizontal surface. At the magnetic equator, the magnetic field lines are perfectly parallel to the Earth's surface, resulting in an angle of zero. D) zero.
