An accelerated electron has a speed of $\displaystyle 5 \times 10^6 \mathrm{~ms}^{-1}$ with an uncertainty of $\displaystyle 0.02 \%$. The uncertainty in finding its location while in motion is $\displaystyle x \times 10^{-9} \mathrm{~m}$. The value of $\displaystyle x$ is \_\_\_\_. (Nearest integer) [Use mass of electron $\displaystyle =9.1 \times 10^{-31} \mathrm{~kg}, \mathrm{~h}=6.63 \times 10^{-34} \mathrm{Js}, \pi=3.14$ ]
