A) \[2\times {{10}^{7}}N\]
B) \[2\times {{10}^{9}}N\]
C) \[3\times {{10}^{-5}}N\]
D) \[1\times {{10}^{5}}N\]
Correct Answer: D
Solution :
\[F=yA\propto \Delta t\] \[=2\times {{10}^{11}}\times 40\,\times {{10}^{-4}}\,\times 1.2\,\times {{10}^{-5}}\times 10\] \[=9.6\,\times {{10}^{4}}=1\times {{10}^{5}}N\]You need to login to perform this action.
