Question

plz give me the solution of abovequestion​

Answer 1

capicitance of earth will be 12800

Answer 2

the formula for capacitance is q/v.

formula for electric field =kq/r2.

formula for electric potential = kq/r.

by Abv relation c= k/r.

c=6400*1000/9*10 raise to power 9

c=711.11micro farad
