The weight of an empty balloon on a spring balance is W1. The weight becomes W2 when the balloon is filled with air. Let the weight of the Air itself be $\omega$ neglect the thickness of the balloon when it is filled with air. Also neglect the difference in the densities of air inside and outside the balloon.

  1. $\text{W}_2=\text{W}_1$

  2. $\text{W}_2=\text{W}_1+\omega$

  3. $\text{W}_2<\text{W}_1+\omega$

  4. $\text{W}_2>\text{W}_1$
