A disc of mass m and radius R, is placed on a smooth text service fixed surface . Point A is the geometrical centre of the disc while point B is the centre of mass of the disc . The moment of inertia of the dics about an axis through its centre of mass and perpendicular to the plane of the figure is I .A constant force F is applied to the top of the disc . The acceleration of the centre A of the disc at the instant B is below A (on the same vertical line ) will be :
