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]

A body of mass M is hanging by an inextensible string of mass m. If the free end of the string accelerates up with constant acceleration a find the variation of tension in the string as a function of the distance measured from the mass M (bottom of the string).
