A seagoing crane lifts a sealed safe from a sunken ship. The average density of the safe is 5.3 grams/cc and its mass is 120 kg. What is the tension in the lifting cable when the safe is still submerged?
Pressure = density *gravity* height*
Buoyant force = mg
The Attempt at a Solution
I calculated 5300kg/m^2 * 9.81 m/s^2 * 120 kg
The above is what I got so far but I'm not sure I'm doing it right. Any help would be greatly appreciated.
