A lunch tray is being held in one hand, as the figure illustrates. The mass of the tray itself is 0.195 kg, and its center of gravity is located at its geometrical center. On the tray is a 1.00-kg plate of food and a 0.230-kg cup of coffee. Obtain (a) the force 7 exerted by the thumb and (b) the force exerted by the four fingers. Both forces act perpendicular to the tray, which is being held parallel to the ground. 0.400 0240m 100m ,0600 (a) Number Units (b) Number I Units
