At a certain location a compass points 150 west of geographic north. The north tip of the magnetic needle, of a dip circle placed in the plane of the magnetic meridian, points 600 above the horizontal. If the horizontal component of earth’s magnetic field is measured to be 0.2G, the magnitude and direction of the earth’s field at that location, are
(1) 0.4G, directed upward of the horizontal line, in the vertical plane, 15° west of geographic north plane
(2) 0.4G, directed downward of the horizontal line, in the vertical plane, 15° west of geographic north plane
(3) 0.4G, directed upward of the horizontal line, in the vertical plane, 15° east of geographic north plane
(4) 0.4G, directed downward of the horizontal line, in the vertical plane, 15° east of geographic north plane
