A) \[4\times {{10}^{5}}\]
B) \[1\times {{10}^{5}}\]
C) \[2\times {{10}^{5}}\]
D) \[1\times {{10}^{4}}\]
Correct Answer: B
Solution :
If length of the wire is doubled then strain = 1 Y = \[\text{Stress}=\frac{\text{Force}}{\text{Area}}\]= \[\frac{2\times {{10}^{5}}}{2}={{10}^{5}}\frac{dyne}{c{{m}^{2}}}\]You need to login to perform this action.
