A) \[6.25\times {{10}^{17}}\]
B) \[6.25\times {{10}^{15}}\]
C) \[1.6\,\times {{10}^{16}}\]
D) \[1.6\,\times {{10}^{-16}}\]
Correct Answer: B
Solution :
\[q=it\] \[ne=it\,\Rightarrow n=\frac{it}{e}\] \[=\frac{1\times {{10}^{-3}}\times 1}{1.6\times {{10}^{-19}}}=6.25\times {{10}^{15}}\]You need to login to perform this action.
