A) \[\frac{2T}{rJ}\]
B) \[\frac{3T}{RJ}\]
C) \[\frac{3T}{J}\left( \frac{1}{r}-\frac{1}{R} \right)\]
D) \[\frac{2T}{J}\left( \frac{1}{r}-\frac{1}{R} \right)\]
Correct Answer: C
Solution :
Rise m temperature, \[\Delta \theta =\frac{3T}{JSd}\,\left( \frac{1}{r}-\frac{1}{R} \right)\] \[\therefore \,\,\Delta \theta =\frac{3T}{J}\,\left( \frac{1}{r}-\frac{1}{R} \right)\] (For water \[S=1\] and \[d=1\])You need to login to perform this action.
