Solution

The correct option is D any direction it is released
Since in a plane perpendicular to the magnetic meridian the earth's horizontal component of magnetic field is zero therefore, it will stay in any direction.
Because in that plane it will only experience earth's vertical component of the magnetic field.

A magnetic needle is free to rotate in a vertical plane which makes an angle of $60^{0}$ with the magnetic meridian. If the needle stays in a direction making an angle of tan $^{- 1} (\frac{2}{\sqrt{3}})$ with the horizontal, what would be the dip at that place ?
