A) \[4mA\]
B) \[2mA\]
C) \[3.6mA\]
D) \[1.8mA\]
Correct Answer: B
Solution :
The rate of heat flow, \[\frac{Q}{t}=\frac{KA\Delta \theta }{l}\] \[6000=\frac{200\times 0.75\times \Delta \theta }{1}\] \[\Delta \theta =\frac{6000\times 1}{200\times 0.75}\] \[={{40}^{o}}C\]You need to login to perform this action.
