The earth has volume V and surface area A then it's capacitance would be :
Answered by admin @
If we assume shape of earth be solid spherical.
then, the volume of earth = 4/3πR³
where R is radius of earth.
given, volume of earth = V = 4/3πR³
surface area of earth = A = 4πR²
so, V/A = (4/3 R³)/4πR²
or, V/A = R/3
or, R = 3V/A
now, capacitance of earth =
=
=
