Explanation:
From the question we are told that
The electric filed is 
Generally according to Gauss law
=> 
Given that the electric field is pointing downward , the equation become
Here 
is the excess charge on the surface of the earth
is the surface area of the of the earth which is mathematically represented as
Where r is the radius of the earth which has a value 
substituting values
So
Here 
s the permitivity of free space with value
substituting values
