A) \[2.012\times {{10}^{5}}N/{{m}^{2}}\]
B) \[2.012\times {{10}^{5}}N/{{m}^{2}}\]
C) \[1.027\times {{10}^{4}}N/{{m}^{2}}\]
D) \[1.027\times {{10}^{4}}/{{m}^{2}}\]
Correct Answer: C
Solution :
The excess pressure inside the air bubble is given by \[{{P}_{2}}-{{P}_{1}}=\frac{2T}{R}\] \[\therefore \] Pressure inside the air bubble \[{{P}_{2}}={{P}_{1}}+\frac{2T}{R}\] Substituting the values, we have \[{{P}_{2}}=1.013\times {{10}^{5}}+\frac{2\times 7.2\times {{10}^{-2}}}{{{10}^{-4}}}\] \[=1.027\times {{10}^{5}}N/{{m}^{2}}\]You need to login to perform this action.
