    An experiment conducted to determine Young s modulus , \[\frac{\eta }{\lambda }[1-{{e}^{-\lambda t}}]\] , where Y = Youngs modulus, T = time, t = torque and 7 = length. Then, the value of \[{{\gamma }_{1}}\]is

    A)  1                                            

    B)  0

    C)  2                                            

    D)  3

    Correct Answer: B

    Solution :

                    We know that       \[[Y]=[M{{L}^{-1}}{{T}^{-2}}],\,\,\sin \theta =[{{M}^{0}}{{L}^{0}}{{T}^{0}}]\] \[[I]=[L]\] Now writing dimensions, we have \[[M{{L}^{-1}}{{T}^{-2}}]=\frac{[{{M}^{0}}{{L}^{0}}{{T}^{0}}][T]\phi [M{{L}^{2}}{{T}^{-2}}]}{[{{L}^{4}}]}\]comparing LHS and RHS, we have                 \[\phi =0\]
