A) \[1.99\times {{10}^{6}}\,volt\]
B) \[2.9\times {{10}^{6}}\,volt\]
C) \[4.99\times {{10}^{6}}\,volt\]
D) \[0.99\times {{10}^{6}}\,volt\]
Correct Answer: A
Solution :
\[V=\frac{1}{4\pi {{\varepsilon }_{0}}}.\frac{(Ze)}{r}=9\times {{10}^{9}}\times \frac{47\times 1.6\times {{10}^{-19}}}{3.4\times {{10}^{-14}}}=1.99\times {{10}^{6}}V\]
