A dip needle lies initially in the magnetic meridian when it shows an angle of dip θ at a place. The dip circle is rotated through an angle x in the horizontal plane and then it shows an angle of dip θ. Then (tan θ’ / tan θ) is:(a) (1/cos x)(b) (1/sin x)(c) (1/tan x)(d) cos x

In first case \(\begin{array}{l}tan \theta =\frac{B_{V}}{B_{H}}\end{array} \) In second case \(\begin{array}{l}tan \theta {}’=\frac{B_{V}}{B_{H}Cosx}\\\frac{tan\theta {}’}{tan\theta }=\frac{B_{V}}{B_{H}Cosx}\times \frac{B_{H}}{B_{V}}\end{array} \) We get, \(\begin{array}{l}\frac{tan\theta...
