    The equation of the tangent to the curve\[{{R}_{1}}\]at the point, where the ordinate and the abscissa are equal, is

    A) \[{{R}_{2}}\]

    B) \[{{Q}_{1}}\]

    C) \[{{Q}_{2}}\]

    D) None of the above

    Correct Answer: C

    Solution :

                    Given, \[4\mu F\] \[10\mu F\]        \[8\mu F\] \[120\mu F\]      \[\omega \] \[R/2\]  \[\frac{4\omega }{5}\]   (since,\[\frac{2\omega }{5}\]) Now,     \[\frac{3\omega }{5}\] \[\frac{2\omega }{3}\]   \[\mu =\frac{3}{2}\]       On differentiating w.r.t. x, we get \[\mu =\frac{4}{3}\] \[{{\sin }^{-1}}\left( \frac{9}{8} \right)\] \[{{45}^{o}}\] \[{{60}^{o}}\]Equation of tangent is \[{{\sin }^{-1}}\left( \frac{8}{9} \right)\]                 \[\beta =0.\text{1}\]      \[{{P}_{1}}\]
