    A dip needle arranged to move freely in the magnetic meridian dips by an angle\[\theta \]. If the vertical plane in which the needle moves is rotated through an angle a to the magnetic meridian, then the needle will dip by an angle

    A)  \[\theta \]                                         

    B)  \[\alpha \]

    C)  more than\[\theta \]                   

    D)  less than\[\theta \]

    Correct Answer: C

    Solution :

                                    In this question, \[cos\,\alpha <1\] ie,        \[\frac{1}{cos\,\alpha }>1\] or          \[\frac{\tan \theta '}{\tan \theta }>1\] or            \[\tan \theta '>\tan \theta \] or               \[\theta '>\theta \] ie, angle of apparent dip is more than angle of actual dip\[\theta \].
