A) \[3.5\times {{10}^{5}}V\]
B) \[3.5\times {{10}^{4}}V\]
C) \[4.5\times {{10}^{4}}V\]
D) \[4.5\times {{10}^{5}}V\]
Correct Answer: C
Solution :
(c) \[4.5\times {{10}^{4}}V\] Here, \[q=5\times {{10}^{-7}}C,\,r=10\,cm=0.1\,m\] Potential \[V=\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{q}{r}=\frac{9\times {{10}^{9}}\times 5\times {{10}^{-7}}}{0.1}=4.5\times {{10}^{4}}V\]You need to login to perform this action.
