A) \[~35N/{{m}^{-2}}\]
B) \[~70\text{ }N/{{m}^{2}}\]
C) \[~140\text{ }N/{{m}^{2}}\]
D) 0
Correct Answer: C
Solution :
Let the excess pressure be\[\Delta P\] \[\Delta P=\frac{2T}{R}=\frac{2\times 70\times {{10}^{-3}}}{{{10}^{-3}}}=140\,N/{{m}^{2}}\] Hence, the correction option is [c].You need to login to perform this action.
