A) \[{{10}^{8}}N/{{m}^{2}}\]
B) \[{{10}^{7}}N/{{m}^{2}}\]
C) \[{{10}^{6}}N/{{m}^{2}}\]
D) \[{{10}^{5}}N/{{m}^{2}}\]
Correct Answer: A
Solution :
[a] \[Y=\frac{F}{A}\times \frac{L}{\Delta L}=\frac{100}{2\times {{10}^{-4}}}\times \frac{2}{1\times {{10}^{-2}}}={{10}^{8}}N/{{m}^{2}}\]You need to login to perform this action.
