Three objects of identical mass attached to strings are suspended in a large tank of liquid, as shown above.
(a) Must all three strings have the same tension?
____
Yes ____ No
Justify your answer.
Object A has a volume of 1.0×10−5m3 and a density of 1300kgm3. The tension in the string to which object A is attached is 0.0098 N .
(b) Calculate the buoyant force on object A .
(c) Calculate the density of the liquid.
(d) Some of the liquid is now drained from the tank until only half of the volume of object A is submerged. Would the tension in the string to which object A is attached increase, decrease, or remain the same?
____ Increase ____ Decrease ____ Remain the same
Justify your answer.
