  • question_answer
    An aircraft executes a horizontal loop of radius km with a steady speed of \[900\text{ }km/h\]. The ratio of centripetal acceleration to acceleration due to gravity is \[\left[ \text{g = 9}\text{.8 m/}{{\text{s}}^{\text{2}}} \right]\]

    A) 6.38     

    B)        9.98  

    C) 11.33   

    D)        12.13

    Correct Answer: A

    Solution :

    [a] \[{{\text{a}}_{c}}=\frac{{{\text{v}}^{\text{2}}}}{\text{r}}=\frac{{{\left( 250 \right)}^{2}}}{{{10}^{3}}}=62.5\text{ m/}{{\text{s}}^{2}}\] \[\Rightarrow {{\text{a}}_{\text{c}}}\text{/g}=\frac{62.5}{9.8}=6.38\]
