A) \[{{10}^{7}}\,\text{volt}\]
B) \[{{10}^{6}}\,\text{volt}\]
C) \[{{10}^{5}}\,\text{volt}\]
D) \[{{10}^{4}}\,\text{volt}\]
Correct Answer: C
Solution :
Charge, \[Q=10\mu C=100\times {{10}^{-6}}C={{10}^{-4}}C\] Distance, d = 9 m (given) The relation for the potential is given by \[V=\frac{1}{4\pi {{\varepsilon }_{0}}}\times \frac{Q}{d}=9\times {{10}^{9}}\times \frac{{{10}^{-4}}}{9}\] \[={{10}^{5}}\,\text{volt}\]You need to login to perform this action.
