The Earth produces an inwardly directed electric field of magnitude 150V/m near its surface. (a) What is the potential of the Earth's surface relative to V=0 at r=[infinity]? (b) If the potential of the Earth is chosen to be zero, what is the potential at infinity? (Ignore the fact that positive charge in the ionosphere approximately cancels the Earth's net charge; how would this affect your answer?)

a

The potential of the earth surface is  

b

when the potential of the earth is zero the charge is choose to be negative this implies that  the potential at infinity would be and (Ignore the fact that positive charge in the ionosphere approximately cancels the Earth's net charge the potential at the surface increase and the electric field remains the same

Explanation:

From the question we are told that

      The magnitude  electric field is  

The potential of the earth surface when  V = 0 and   is mathematically represented as

Where q is the charge on the surface of the earth  which is negative

           R is the radius of the earth

when the potential of the earth is zero the charge is choose to be negative

Then the potential at infinity would be

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
