A) 0.6
B) 0.4
C) 02
D) Zero
Correct Answer: B
Solution :
[b] \[\frac{dV}{V}=(1+2\sigma )\frac{dL}{L}\] \[\frac{dV}{V}=2\times 2\times {{10}^{-3}}=4\times {{10}^{-3}}\] \[\left[ \because \sigma =0.5=\frac{1}{2} \right]\] \[\therefore \]Percentage change in volume\[=4\times {{10}^{-1}}\]\[=0.4%\]You need to login to perform this action.
