The elongation of a wire on the surface of the earth is $10^{-4}$ m. The same wire of same dimensions is elongated by $6 \times 10^{-5}$ m on another planet. The acceleration due to gravity on the planet will be ............ $\mathrm{ms}^{-2}$. (Take acceleration due to gravity on the surface of earth = $10 \mathrm{~m} / \mathrm{s}^{-2}$)
