Question

Calculate capacitance of earth.Given radius of earth is 6400Km

Answer 1

apacitance C of Sphere of Radius Ris given by, C = 4πε0R .

If we assume earth as sphere of radius R, then capacitance of earth is 4πε0R , where R is radius of earth.

Radius of earth = 6378 km.

Capacitance of earth = 4π×8.854×10-12 ×6378×103 = 7.096×10-4 Farad.

Hope it helps

Answer 2

Answer: 711 MF

Explanation:As we know C--4^E0r

Here 4^E0 - 1/9 * 10(9)

r -- 6400Km -- 6.4 * 10(6) m

Now C -- 6.4*10(6) / 9*10(9)

-- 711MF
