Question

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 10-2m3 and the tension in the

cable is 90.0N. What is the buoyant force exerted by the water on the sphere? 147N

Answer 1

Beyond. Force

F=$\rho gv$

Put value

$$F=10^3\times9.8\times1.50\times10^{-2}=147N$$
