Figure Q l3.33 shows aI 00 g block of copper (p =8900 kg!m3) and a I 00 g blockof aluminum (p = 2700 kg!m3)connected by a massless stringthat runs over two massless,frictionless pulleys. The twoblocks exactly balance, since they have the same mass. Now suppose that the whole systemis submerged in water. What will happen?A. The copper block will fall, the aluminum block wi ll rise.B.
