A) \[9\times {{10}^{5}}V\]
B) \[8\times {{10}^{6}}V\]
C) \[80\,\,V\]
D) \[9\,V\]
Correct Answer: B
Solution :
(b) \[8\times {{10}^{6}}V\] We know that, \[V=\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{q}{r}=\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{Ze}{r}\] \[=\frac{9\times {{10}^{9}}\times 50\times 1.6\times {{10}^{-19}}}{9\times {{10}^{-13}}\times {{10}^{-2}}}=8\times {{10}^{6}}V\]You need to login to perform this action.
