A lunch tray is being held in one hand, as the figure illustrates. The mass of the tray itself is 0.247 kg, and itscenter of gravity is located at its geometrical center. On the trayis a 1.01-kg plate of food and a 0.254-kg cup of coffee. Obtain(a) the force exerted by the thumb and(b) the force exerted by the four fingers. Both forcesact perpendicular to the tray, which is being held parallel to the ground.
