A) \[47.7\ m\]
B) 4.77 \[m\]
C) 477 \[m\]
D) None of the above
Correct Answer: B
Solution :
\[C=\frac{{{\varepsilon }_{0}}AK}{d}=4\pi {{\varepsilon }_{0}}r\] r = Radius of sphere of equivalent capacity Þ \[r=\frac{AK}{4\pi d}=\frac{100\times {{10}^{-4}}\times 6}{1\times {{10}^{-3}}\times 4\times 3.14}\]\[=\frac{15}{3.14}=4.77\,m\]You need to login to perform this action.
