360664 A dip circle shows apparent dip of \(60^{\circ}\) at a place where the true dip is \(45^{\circ}\). If the dip circle is rotated by \(90^{\circ}\) the apparent dip will be equal to

1 \(\tan ^{-1} \sqrt{\dfrac{2}{3}}\)
2 \(\sin ^{-1} \sqrt{\dfrac{2}{3}}\)
3 \(\cos ^{-1} \sqrt{\dfrac{2}{3}}\)
4 \(\cot ^{-1} \sqrt{\dfrac{2}{3}}\)

360665 If a magnet is suspended at angle \(30^{\circ}\) to the magnetic meridian, the dip needle makes angle of \(45^{\circ}\) with the horizontal. The real dip is

1 \(\tan ^{-1}(\sqrt{3} / 2)\)
2 \(\tan ^{-1}(\sqrt{3})\)
3 \(\tan ^{-1}\left(\dfrac{3}{\sqrt{2}}\right)\)
4 \(\tan ^{-1}\left(\dfrac{2}{\sqrt{3}}\right)\)
