In a plane perpendicular to the magnetic meridian, the dip needle will be (a) vertical (6) horizontal (c) inclined equal to the angle of dip at that place (d) pointing in any direction
Dear Student,
In a plane perpendicular to the magnetic meridian, the dip needle will remain in a vertical since the horizontal component to the earth's field is not effective as the axis of rotation of needle lies in the direction of the horizontal component of the magnetic field.
