Find the buoyant force exerted by the water on the sphere

Reference no: EM13512718

A hollow plastic sphere is held below the surface of a freshwater lake by a cord anchored to the bottom of the lake. The sphere has a volume of 0.700m^3 and the tension in the cord is 890 N .

A. Calculate the buoyant force exerted by the water on the sphere.

B. What is the mass of the sphere?

C. The cord breaks and the sphere rises to the surface. When the sphere comes to rest, what fraction of its volume will be submerged?
