    Two tangent galvanometer having coils of the same radius are connected in series. A current flowing in them produces deflection of \[60{}^\circ \] and \[45{}^\circ \] respectively. The ratio of the number of turns in the coils is

    A)  4/3                                       

    B) \[={{h}_{1}}+{{h}_{2}}=\frac{245}{2}+\frac{245}{2}=245m\]         

    C)        \[Work=force\times displacement\]                      

    D) \[={{F}_{s}}.d\]

    Correct Answer: C

    Solution :

                    For tangent galvanometer \[=15mm=1.5cm\] \[C=\frac{{{\varepsilon }_{0}}A}{d}\] \[=\frac{8.854\times {{10}^{-12}}\times 5\times {{10}^{-4}}}{0.885\times {{10}^{-2}}}=0.5pF\] \[=8C=8\times 0.5=4pF\]
