A) \[-13.6\,\,V\]
B) \[-27.2\,\,V\]
C) \[27.2\,\,V\]
D) \[13.6\,\,V\]
Correct Answer: C
Solution :
Using the formula \[V=\frac{1}{4\pi {{\varepsilon }_{0}}}=\frac{Ze}{r}\] (for hydrogen nuclear\[Z=1\] \[e=1.6\times {{10}^{-19}}C\] \[r=0.53\times {{10}^{-10}}m)\] \[=\frac{9\times {{10}^{9}}\times 1.6\times {{10}^{-19}}\times 1}{0.53\times {{10}^{-10}}}=27.2\,\,V\]You need to login to perform this action.
