A particle of mass $\displaystyle 10$ g moves in a straight line with retardation $\displaystyle 2 x$, where $\displaystyle x$ is the displacement in SI units. Its loss of kinetic energy for above displacement is $\displaystyle \left(\frac{10}{x}\right)^{-n} \mathrm{~J}$. The value of n will be $\displaystyle \_\_\_\_$
