A) \[8\times {{10}^{-7}}\]
B) \[5\times {{10}^{-11}}\]
C) \[8\times {{10}^{-11}}\]
D) \[5\times {{10}^{7}}\]
Correct Answer: D
Solution :
Energy\[=2eV\] \[e{{V}_{0}}=2eV\Rightarrow {{V}_{0}}=2\] Now, electric field \[E=\frac{2}{4\times {{10}^{-8}}}=0.5\times {{10}^{8}}\] Hence \[E=5\times {{10}^{7}}\,V{{m}^{-1}}\]You need to login to perform this action.
