A) \[2\times {{10}^{9}}\,N{{m}^{-2}}\]
B) \[4\times {{10}^{9}}\,N{{m}^{-2}}\]
C) \[8\times {{10}^{9}}\,N{{m}^{-2}}\]
D) \[16\times {{10}^{9}}\,N{{m}^{-2}}\]
Correct Answer: A
Solution :
Shearing modulus of cube \[\eta =\frac{Fl}{A\Delta l}=\frac{8\times {{10}^{3}}\times 40\times {{10}^{-3}}}{(40\times {{10}^{-3}})\times (0.1\times {{10}^{-3}})}\] \[=2\times {{10}^{9}}\,N{{m}^{-2}}\]You need to login to perform this action.
