\mathrm{\text { volume } 2 \mathrm{~cm} \text { balloon is }=V}

\mathrm{\text { If volume ot } 10 \mathrm{~cm} \text { Radius }=\frac{4}{3} M(10)^{3}}

\mathrm{1 \quad=125 \mathrm{~V}}

\mathrm{\text { so Pressure will become } \frac{1}{125} \text { time }}

\mathrm{\begin{aligned} & =\frac{1}{125} \times 50 \times 10^{-3} \\ & =.4 \times 10^{-3} \end{aligned}}
