A homogeneous flexible rope rests on a wedge whose side edges make angles α and β with the horizontal (refer figure). The central part of the rope lies on the upper rib C of the wedge. With what acceleration should the wedge be pulled to the left along the horizontal plane in order to prevent the displacement of the rope with respect tot the wedge? [Consider all surfaces to be smooth]
