Question

calculate the capacitance of the earth of radius 6380 km​

Answer 1

q=CV

C=q/V

C=4π€°r

=6380×10^3÷9×10^9

=7.0888889e+14

Answer 2

Answer:

7.088× 10^-9

radius of Earth is 6380km

1km = 1000m

6380km = 6380×1000m

= 6380× 10^3 m

capacitance of the earth of radius

c= 4πE. r

c= 1/9*10^9 × 6380* 10^3

= 7.088×10*-4
