NARRATIVE
             The cart will remain stationary when all forces on it are balanced.

            The mass of the cart is 400 g. Hang 345 g from a string whose tension is perpendicular to the inclined plane. Hang 200 g from a string whose tension is parallel to the plane.

            The cart should just rest on the plane so that the plane may be removed while the cart remains stationary.
