A tight rope walker in a circus holds a long flexible pole to help stay balanced on the rope. Honding the pole horizontally and perpendicular to the rope helds the performer.

A homogeneous flexible rope rests on a wedge whose side edges make angles alpha and beta with the horizontal. 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 to the wedge? [Consider all surfaces to be smooth]
