Find out the capacitance of the earth ? (Radius of the earth = 6400 km)

Explanation

To find the capacitance of the Earth, we can use the formula for the capacitance of a sphere, which is given by:

\[ C = 4 \pi \epsilon_0 r \]

where:
- \( C \) is the capacitance,
- \( \epsilon_0 \) is the permittivity of free space, approximately \( 8.854 \times 10^{-12} \, \text{F/m} \),
- \( r \) is the radius of the sphere.
