A) \[0.008{{/}^{o}}C\]
B) \[0.006{{/}^{o}}C\]
C) \[0.004{{/}^{o}}C\]
D) \[0.001{{/}^{o}}C\]
Correct Answer: A
Solution :
Using \[{{R}_{{{T}_{2}}}}={{R}_{{{T}_{1}}}}[1+\alpha ({{T}_{2}}-{{T}_{1}})]\] Þ \[{{R}_{100}}={{R}_{50}}[1+\alpha (100-50)]\] Þ \[7=5\,[1+(\alpha \times 50)]\] Þ \[\propto \,=\,\frac{(7-5)}{250}=0.008{{/}^{o}}C\]
