A block is resting on a frictionless surface as shown in the figure attached with this post. Calculate the minimum force F required so that the block will topple? The dimensions of the block, free body diagram and other details are there in the picture attached.(adsbygoogle = window.adsbygoogle || []).push({});

Now, since the surface is frictionless, in the horizontal direction F=ma, where m=mass of the block and, a=the acceleration in the horizontal direction.

In the vertical direction, N=mg, where N is normal reaction force by the surface. The third equation is the moment equation.

The problem is very easy and fundamental, but I am confused as to whether I should balance the torques about the centre of mass or about the bottom right corner point? The difference between this and other toppling problem is that the block will accelerate as soon as the force is applied because the surface is frictionless, so it will kind of slide and topple instead of toppling at a fixed position. Please help me out with this!
