Consider a uniform cubical box of side a on a rough floor that is to be moved by applying minimum possible force F at a point b above its centre of mass (see figure). If the coefficient of friction is $\displaystyle \mu=0.4$, the maximum possible value of $\displaystyle 100 \times \frac{\mathrm{b}}{\mathrm{a}}$ for box not to topple before moving is
