A helium filled balloon is tied to a 2.00 m long, .050 0-kg uniform string. The balloon is spherical with a radius of 0.400 m. When released, it lifts a length h of string and then remains in equilibrium. Determine the value of h. The envelope of the balloon has mass of 0.250 kg.© BrainMass Inc. brainmass.com March 4, 2021, 6:10 pm ad1c9bdddf
