    An aircraft executes a horizontal loop with a speed of 150 m/s with its wings banked at an angle of \[12{}^\circ .\] The radius of the loop is : \[\left( g=10m/{{s}^{2}} \right)\]

    A) 10.6 km

    B) 9.6 km

    C) 7.4 km

    D) 5.8 km

    Correct Answer: A

    Solution :

    [a] \[tan\,\theta =\frac{{{v}^{2}}}{rg}\] \[tan{{12}^{o}}={{\left( 150 \right)}^{2}}/r\times 10\] \[\Rightarrow r=\frac{2250}{0.2125}=10.6km\]
