An empty spherical weather balloon with a mass of 5 kg has a radiusof 2.879 m when fully inflated with helium. It is suppose to carrya small load of instruments having a mass of 10 kg. Taking air andhelium to have densities of 1.16 kg/m3 and 0.160kg/m3, respectively, what will be the acceleration of the balloon and load immediately after it is released?
