a.) Calculate the buoyant force (in N) on a 2.00 L
helium balloon.
____ N (upward)
(b) Given the mass of the rubber in the balloon
is 2.00 g, what is the net vertical force (in N) on the
balloon if it is let go? You can neglect the volume of the
rubber.
_____ N (upward)
Use Density of air= 1.29
kg/m3 and
Density of helium = 0.18 kg/m3
