An object ' o ' is placed at a distance of $\displaystyle 100$ cm in front of a concave mirror of radius of curvature $\displaystyle 200$ cm as shown in the figure. The object starts moving towards the mirror at a speed $\displaystyle 2 \mathrm{~cm} / \mathrm{s}$. The position of the image from the mirror after $\displaystyle 10$ s will be at \_\_\_\_ cm.
