  • question_answer
    If the earth is treated as a sphere of radius R and mass M having period of rotation T, then its angular momentum about its axis of rotation is

    A) \[-\text{ 245 kJ mo}{{\text{l}}^{-\text{1}}}\]                       

    B) \[-\text{ 93 kJ mo}{{\text{l}}^{-\text{1}}}\]  

    C) \[\text{245 kJ mo}{{\text{l}}^{\text{-1}}}\]

    D) \[2HI(g){{H}_{2}}(g)+{{I}_{2}}(g)\]

    Correct Answer: C

    Solution :

    Angular momentum \[1-\frac{25}{100}\,\,\,\,\,4\times \frac{25}{100}=0.75=1\] \[{{K}_{p}}=\frac{{{({{p}_{{{s}_{2}}}})}^{4}}}{{{P}_{{{s}_{8}}}}}=\frac{{{(1)}^{4}}}{0.75}=1.33at{{m}^{3}}\]
