    rectangular block
    The center of mass of the block would be at the center of the block assuming it to be made of an homogenous material. So the center of mass would be a point originating 5cm within the side of the block and 10cm within from the top.

    You just calculate the angle at which the horizontal component of the normal force creates a moment about the bottom edge of the block that is greater than the moment created by the vertical component of the normal force.

    Simple as that.
