    In a moving coil galvanometer, the deflection of the coil \[[\exp (7.62)=2038.6,k=1.4\times {{10}^{-24}}J/k]\] is related to the electric current i by the relation

    A) \[2037.6\times {{10}^{-3}}A\]                    

    B) \[203.76\times {{10}^{-3}}A\]

    C) \[20.376\times {{10}^{-3}}A\]                    

    D) \[2.0376\times {{10}^{-3}}A\]

    Correct Answer: B

    Solution :

                    In equilibrium position of the coil \[\overset{0}{\mathop{A}}\,\] \[\overset{0}{\mathop{A}}\,\] where k = proportionality constant \[\overset{0}{\mathop{A}}\,\] Hence, \[y=5\sin \frac{\pi x}{3}\cos 40\pi t\]
