A) \[\text{20 }\!\!{}^\circ\!\!\text{ C}\]
B) \[\text{40 }\!\!{}^\circ\!\!\text{ C}\]
C) \[\text{80 }\!\!{}^\circ\!\!\text{ C}\]
D) \[\text{100 }\!\!{}^\circ\!\!\text{ C}\]
Correct Answer: B
Solution :
\[\frac{Q}{t}=\frac{KA\theta }{l}\] \[\Rightarrow \] \[6000=\frac{200\times 0.75\times \theta }{1}\] \[\therefore \] \[\Delta \theta =\frac{6000\times 1}{200\times 0.75}=40{{\,}^{o}}C\]You need to login to perform this action.
