A) \[{{10}^{4}}V\]
B) \[{{10}^{6}}V\]
C) \[{{10}^{5}}V\]
D) \[{{10}^{7}}V\]
Correct Answer: C
Solution :
(c) \[{{10}^{5}}V\] Here, \[q=100\mu C=100\times {{10}^{-6}},\,r=9m\] \[V=\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{q}{r}\] \[=\frac{9\times {{10}^{9}}\times 100\times {{10}^{-6}}}{9}={{10}^{5}}V\]You need to login to perform this action.
