Question:

Figure Q13.33 shows a \(100 \mathrm{~g}\) block of copper \((ho=\) \(8900 \mathrm{~kg} / \mathrm{m}^{3}\) ) and a \(100 \mathrm{~g}\) block of aluminum \(\left(ho=2700 \mathrm{~kg} / \mathrm{m}^{3}\right)\) connected by a massless string that runs over two massless, frictionless pulleys. The two blocks exactly balance, since they have the same mass. Now suppose that the whole system is submerged in water. What will happen?

A. The copper block will fall, the aluminum block will rise.

B. The aluminum block will fall, the copper block will rise.

C. Nothing will change.

D. Both blocks will rise.. image text in transcribed
