A) \[6\times {{10}^{-\,10}}\,\text{kg/c}{{\text{m}}^{\text{2}}}\]
B) \[6\times {{10}^{-\,10}}\,\text{kg/c}{{\text{m}}^{\text{2}}}\]
C) \[2.4\times {{10}^{3}}\,\text{kg/c}{{\text{m}}^{\text{2}}}\]
D) \[2.4\times {{10}^{4}}\,\text{kg/c}{{\text{m}}^{\text{2}}}\]
Correct Answer: C
Solution :
\[{{\sigma }_{t}}=E\,\alpha .\Delta \theta \] \[=2\times {{10}^{6}}\times 12\times {{10}^{-6}}\times 100\] \[=2.4\times {{10}^{3}}\,\text{kg/c}{{\text{m}}^{\text{2}}}\]You need to login to perform this action.
