A) 2.4%
B) 10%
C) 0.15%
D) 1.5%
Correct Answer: D
Solution :
\[\text{T=}\frac{rhg}{2}\times {{10}^{3}}\] \[\frac{\Delta T}{T}=\frac{\Delta r}{r}+\frac{\Delta h}{h}+0\] \[100\times \frac{\Delta T}{T}=\left( \frac{{{10}^{-2}}\times .01}{1.25\times {{10}^{-2}}}+\frac{{{10}^{-2}}\times .01}{1.45\times {{10}^{-2}}} \right)100\] \[=(0.8+0.689)\] \[=(1.489)\] \[100\times \frac{\Delta T}{T}=1.489%\] \[\simeq 1.5%\]You need to login to perform this action.
