A 10.8 kg block of metal is suspended from a scale and immersed in water, as in the figure below. The dimensions of the block are 12.0 cm 10.4 cm 10.4 cm. The 12.0 cm dimension is vertical, and the top of the block is 5.00 cm below the surface of the water.


(a) What are the forces exerted by the water on the top and bottom of the block? Take P0 = 1.0130 105 N/m2.


Ftop: 243.36 N: Your response differs from the correct answer by more than 10%. Double check your calculations. N



Fbottom: 19115.1168: Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. N

(b) What is the reading of the spring scale?
9.50208 N: Your response differs from the correct answer by more than 10%. Double check your calculations. N

All my answers were wrong!
