    The angle of dip at a place is \[40.6{}^\circ \] and the intensity of the vertical component of earths magnetic field \[V=6\times {{10}^{-5}}\] tesla. The total intensity of the earths magnetic field \[I\] at this place is :

    A)  \[7\times {{10}^{-5}}\] tesla      

    B)  \[6\times {{10}^{-5}}\] tesla      

    C)         \[5\times {{10}^{-5}}\] tesla    

    D)         \[9.2\times {{10}^{-5}}\] tesla

    Correct Answer: D

    Solution :

    Using the formula \[V=I\sin \theta \] \[I=\frac{V}{\sin \theta }=\frac{6\times {{10}^{-5}}}{\sin 40.6}\] \[=9.2\,\times {{10}^{-5}}\,tesla\]
