A 4.0-kg cylinder of solid iron is supported by a string while submerged in water. What is the tension in the string? The density of iron is 7860 kg/m3 and that of water is 1000 kg/m3.
A) 34 N B) 2.5 N C) 24 N D) 40 N E) 20 N

the tension is just the weight of the iron, minus the weight of the water displaced.
It is A, 34N
