A thin spherical shell is charged by some source. The potential difference between the two points \({C}\) and \({P}\) (in \({V}\) ) shown in the figure is:
\({\left(\right.}\) Take \({\dfrac{1}{4 \pi \varepsilon_{0}}=9 \times 10^{9} S I}\) units \({)}\)

Assertion :
For practical purposes, the earth is used as a reference at zero potential in electrical circuits.
Reason :
The electrical potential of a sphere of radius \(R\) with charge \(Q\) uniformly distributed on the surface is given by \(\dfrac{Q}{4 \pi \varepsilon_{0} R}\). As \(R\) is very large and \(Q\) is very small (total charge of earth) so the net potential of earth is approximately zero.
