A) \[\frac{5W}{2}\]
B) \[\frac{\pi }{2}\]
C) \[\sigma =\text{5}.\text{67}\times \text{1}{{0}^{-\text{8}}}\text{W}-{{\text{m}}^{\text{2}}}{{\text{K}}^{\text{-4}}}\]
D) 2W
Correct Answer: A
Solution :
Work done \[\therefore \] \[Ag=108\] \[T\propto \frac{1}{V}\] \[\text{6}\times \text{1}{{0}^{-\text{7}}}\text{A}-{{\text{m}}^{\text{2}}}\] \[\text{5 g}/\text{c}{{\text{m}}^{\text{3}}}\] Hence \[\text{8}\text{.3}\times \text{1}{{0}^{\text{6}}}\]
