A) 5.6
B) 2.5
C) 1.8
D) 1.4
Correct Answer: C
Solution :
\[{{k}_{1}}\,\,=\,\,\frac{1240}{350}\,-\,W\,\,=\,\,3.54\,\,-\,\,W\] \[{{k}_{2}}\,\,=\,\,\frac{1240}{540}-W\,\,\,=\,\,2.3\,\,-\,\,W\] \[\frac{{{k}_{1}}}{{{k}_{2}}}\,=\,\frac{3.5u\,\,-\,\,W}{2.3\,-\,W}\,\,=\,\,\frac{4}{1}\] \[3.54\,\,-W\,\,=\,\,9.2\,\,-\,\,uW\] \[3W\,\,=\,\,5.66\,\,\] \[W\,\,=\,\,1.8\,eV\,\,\] Option (c)You need to login to perform this action.
