An undersea research chamber is spherical with an external diameter of 5.50 meter. The mass of the chamber, when occupied, is 88300 kilogram. It is anchored to the sea bottom by a cable. The density of seawater is 1025 kg/m3.
Part A Obtain the buoyant force on the chamber? Express your answer to three significant figures and include the appropriate units.
Part B Estimate what is the tension in the cable? Express your answer to two significant figures and include the appropriate units.
