A) \[8\times {{10}^{7}}\]
B) \[5\times {{10}^{-11}}\]
C) \[8\times {{10}^{-11}}\]
D) \[5\times {{10}^{7}}\]
Correct Answer: D
Solution :
[d] Energy \[=2\,eV\] |
\[e{{V}_{0}}=2\,eV\] |
\[\Rightarrow \] \[{{V}_{0}}=2\] |
Now, electric field \[E=\frac{2}{4\times {{10}^{-8}}}\] |
\[=0.5\times {{10}^{8}}\] |
\[=5\times {{10}^{7}}\,V{{m}^{-1}}\] |
