Answer to Question #293881 in Molecular Physics | Thermodynamics for Eziekiel

Question

. A plastic spherical balloon is held below the surface of a swimming pool by a cable tied to the bottom of the pool. The sphere has a volume of 1.50 x 10 -2 m 3 and the tension in the cable is 90.0N. What is the buoyant force exerted by the water on the sphere? 147N 

Answer 1

$F=\rho gV,$

$F=1000\cdot 9.8\cdot 0.015=147~N.$
