A helium-filled balloon, whose envelope has a mass of 0.26 kg,
is tied to a 3.6-m long, 0.053-kg string. The balloon is spherical
with a radius of 0.40 m. When released, it lifts a length
h of the string and then remains in equilibrium, as in the
figure below. Determine the value of h. Hint:
Only that part of the string above the floor contributes to the
load being supported by the balloon. (The density of air is 1.29
