1.) A spherical ball with a radius of 2.130×10-1 m is completely submerged in a fluid that has a density of 1.023×103 kg/m3. What is the volume of the fluid displaced by the ball? (Since the ball is completely submerged, this is the same as the volume of the ball.)
2.) What is the weight of the fluid displaced by the ball?
3.) What is the buoyant force acting on the ball?
