Question

if atmospheric electric field is approximately 150 volt per metre and radius of the earth is 6400 kilometre then the total charge on the earth surface is​

Answer 1

Hey mate ur answer....

E=1/4pieo q/r^2

q = E x r^2/9x10^9

q = 674333.33C

Hope it helps u

Answer 2

Answer:

The total charge on the earth surface is​ $6.8\times10^{5}\ C$

Explanation:

Given that,

Electric field E = 150 V/m

Radius of the earth r = 6400 km

Formula of the electric field is defined as,

$E = \dfrac{kq}{r^2}$

$q=\dfrac{Er^2}{k}$

Where,

E = electric potential

q = charge

r = radius of earth

Put the value into the formula

$q=\dfrac{150\times(6400\times1000)^2}{9\times10^{9}}$

$q=6.8\times10^{5}\ C$

Hence, The total charge on the earth surface is​ $6.8\times10^{5}\ C$
