    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 \[(g= 10 m/{{s}^{2}})\]

    A) 10.6 km            

    B) 9.6 km

    C) 7.4 km             

    D) 5.8 km

    Correct Answer: A

    Solution :

    The angle of banking, \[\tan \,\,\theta =\frac{{{\nu }^{2}}}{rg}\] \[\Rightarrow \,\,\,\,\,\,\,\tan \,\,12{}^\circ =\frac{{{\left( 150 \right)}^{2}}}{r\times 10}\] \[\Rightarrow \,\,\,\,\,r=10.6\,\,\times \,1{{0}^{3}}m\,\,=\,\,10.6\,\,km\]
