A) 0.6
B) 0.4
C) 0.2
D) zero
Correct Answer: B
Solution :
\[\frac{dV}{V}=(1+2\sigma )\frac{dl}{l}\]\[=2\times 2\times {{10}^{-3}}=4\times {{10}^{-3}}\] \[\left[ \because \sigma =0.5=\frac{1}{2} \right]\] \[\therefore \] Percentage change in volume\[=4\times {{10}^{-1}}=0.4%\]You need to login to perform this action.
