    An aircraft executes a horizontal loop with a speed of 150 m/s with its, wings banked at an angle of \[{{12}^{o}}\]. The radius of the loop is \[(g=10\,\,m/{{s}^{2}})\]                                  [Pb. PET 2001]

    A)             10.6 km

    B)                    9.6 km

    C)                         7.4 km            

    D)                                  5.8 km

    Correct Answer: A

    Solution :

                    The angle of banking, \[\tan \theta =\frac{{{v}^{2}}}{rg}\]             Þ \[\tan 12{}^\circ =\frac{{{(150)}^{2}}}{r\times 10}\] Þ \[r=10.6\times {{10}^{3}}\,m=10.6\,km\]
