विकल्प
in horizontal direction only
in vertical direction only
in any direction except vertical and horizontal
in the direction it is released
उत्तर
A dip circle is taken to geomagnetic equator. The needle is allowed to move in a vertical plane perpendicular to the magnetic meridian. The needle will stay in the direction it is released.
Explanation:
At the geomagnetic equator, the needle tries to suspend itself in horizontal direction. But here the needle is restricted to move only in the vertical plane perpendicular to the magnetic meridian. Hence, the needle will stay in the direction it is released.
