A hollow box has a volume of 0.003 m and a mass of m = 2.1 kg. It is filled with some heavy stuff so the total mass (box + heavy stuff) becomes M = 5.0 kg but the total volume is still 0.003 m (a) (8 pts) The box + heavy stuff is put in water (density of water = 1000 kg/m). To prevent it from sinking to the bottom but still completely submerged, a hand must hold the box + heavy stuff. Draw a force diagram, label all the forces on the box+heavy stuff, obtain an equation from applying Newton's laws and find the magnitude of the force exerted by the hand. -8 F box + heavy stuff water (b) (6 pts) The heavy stuff is removed from the box then the hollow box is put in water and it floats on the surface of water. Draw a force diagram, label all the forces on the box, obtain an equation from applying Newton's laws and find the volume of the box that is above the water surface. F 6 water FB
