Answer - (θ) = Arc tan 3/2
The horizontal component of magnetic field at the magnetic meridian = Bh
the horizontal component of magnetic field at 30 degrees with the magnetic meridian = Bh' = Bhcos30 = Bh√3/2
the vertical component(Bv) will be same at both the axis hence
Apparent dip= Bv/Bh' = 2Bv/√3Bh = tan 60
hence true dip= Bv/Bh = tan (θ) ,
(θ) = Arc tan 3/2
