Q: 
A lead sphere with a volume of 1 mL and a silicon sphere with a volume of 1 mL are dropped into water. What is the buoyant force on each sphere? Note: the density of lead is 11 g/mL and the density of silicon is 2.3 g/mL.



A 

The buoyant force is 0.11 N on the lead sphere and 0.023 N on the silicon sphere. 
B 

The buoyant force is 0.00091 N on the lead sphere and 0.0043 N on the silicon sphere. 
C 

The buoyant force on both spheres 11 N. 
D 

The buoyant force on both spheres is 0.01 N.
