A) \[0.5\times {{10}^{-16}}A\]
B) \[2\times {{10}^{12}}A\]
C) \[0.5\times {{10}^{12}}A\]
D) \[2\times {{10}^{-12}}A\]
Correct Answer: A
Solution :
\[i=\frac{nq}{t}=\frac{n(2e)}{t}\] \[={{10}^{4}}\times \frac{2\times 16\times {{10}^{-20}}}{60}\] \[={{10}^{4}}\times \frac{2\times 16\times {{10}^{-20}}}{60}\] \[=(5+same\,\,value)\times {{10}^{-17}}\] \[=\mathbf{0}.\mathbf{5\times 1}{{\mathbf{0}}^{-\mathbf{16}}}\mathbf{Amp}\] (Value of \[\frac{1}{3}\] is not considered because the given options do not require more precise answer)
