A) \[{{10}^{17}}/{{m}^{3}}\]
B) \[{{10}^{15}}/{{m}^{3}}\]
C) \[{{10}^{4}}/{{m}^{3}}\]
D) \[{{10}^{2}}/{{m}^{3}}\]
Correct Answer: A
Solution :
\[n_{i}^{2}={{n}_{h}}{{n}_{e}}\]Þ \[{{({{10}^{19}})}^{2}}={{10}^{21}}\times {{n}_{e}}\] Þ \[{{n}_{e}}={{10}^{17}}/{{m}^{3}}.\]You need to login to perform this action.
