Multiple Choice
A wooden cube, 1 m on all sides and having density 800 kg/m3 , is held under water in a large container by a string, as shown below. The top of the cube is exactly 2 m below the water line. Calculate the difference between the force applied by water to the top and to the bottom faces of the cube (Hint:calculate the two forces, then subtract. Use g=10 m/s2.)
A
Fbot − Ftop = 800 N
B
Fbot − Ftop = 1000 N
C
Fbot − Ftop = 8,000 N
D
Fbot − Ftop = 10,000 N
