At a certain place on earth, the north tip of the magnetic needle of a dip circle placed in the plane of magnetic meridian points 60° below the horizontal. The horizontal component of the earth's magnetic field is measured to be 0.16 G. The magnitude of the earth's magnetic field at the location is:

0.16 G $\frac{0.32}{\sqrt{3}}G$ 0.32 G 0.08 G

0.32 G

The correct answer is Option (3) → 0.32 G
