Answer:
38.5 N/C
Explanation:
The electric field generated by a charged sphere at a point outside the sphere is equivalent to the electric field generated by a single point charge, and it is given by

where
is the Coulomb's constant
Q is the net charge
r is the distance from the centre of the sphere
In this problem, we have


Substituting into the equation, we find

Honest, the map is so tiny, and so fuzzy when I blow it up, I really can't see anything on it clearly. But I think maybe I do see a letter ' C ' in the eastern Mediterranean, with a curved line over to the southern Gaza strip, where it meets Sinai. So I'll say it's the Gaza Strip.
The potential difference between the two points if the work done on the charge is +3.4×10^7 joules would be A. 10volts.
Compared with an Earth year, a galactic year represents time on a grand scale but its not a consistent measurement across the galaxy
