    A cyclist turns around a curve at 15 miles/hour. If he turns at double the speed, the tendency to overturn is [CPMT 1974; AFMC 2003]

    A)             Doubled

    B)                      Quadrupled

    C)             Halved

    D)                      Unchanged

    Correct Answer: B

    Solution :

                    \[F=\frac{m{{v}^{2}}}{r}\] Þ \[F\propto {{v}^{2}}\]. If v becomes double then F (tendency to overturn) will become four times.
