A galaxy is moving away from the earth at a speed of $\displaystyle 286 \mathrm{kms}^{-1}$. The shift in the wavelength of a redline at $\displaystyle 630$ nm is $\displaystyle x \times 10^{-10} \mathrm{~m}$.The value of $\displaystyle x$, to the nearest integer, is \_\_\_\_. [Take the value of speed of light c , as $\displaystyle 3 \times 10^8 \mathrm{~ms}^{-1}$ ]
