de-Broglie wavelength

    \lambda =\frac{h}{mv}=\frac{h}{p}

Kinetic energy =\frac{P^{2}}{2m}

                        =\frac{1}{2m}\left ( \frac{h}{\lambda } \right )^{2}

            K.E =\frac{h^{2}}{2m\lambda ^{2}}

                       =\frac{\left ( 6.626\times 10^{-34} \right )^{2}}{2\times 9.11\times 10^{-31}\times (1\times 10^{-10})^{2}}

                       =2.409\times 10^{-17}J
