← The sloping face of a wedge is smooth and makes 37° with the floor (tan 37° = 0.75). A small block of mass m is placed on this face. The wedge is then pushed so that it moves along the floor with a steady acceleration, as shown in the figure, and the block does not slide on it at all. Taking g = 10 m/s², the acceleration of the wedge and the normal force on the block areA uniform square plate of side 2a has a square of side a cut away from one corner, as shown in the figure. How far is the centre of mass of the remaining plate from the centre of the original square? →
