A) \[6\times {{10}^{-2}}\,N/{\AA}\]
B) \[6\times {{10}^{-9}}N/{\AA}\]
C) \[4\times {{10}^{-5}}\,N/{\AA}\]
D) \[6\times {{10}^{-5}}N/{\AA}\]
Correct Answer: B
Solution :
\[K=Y{{r}_{0}}=20\times {{10}^{10}}\times 3\times {{10}^{-10}}=60\ N/m\] \[=6\times {{10}^{-9}}N/{\AA}\]You need to login to perform this action.
