Solve the all parts of given question:
Question: In fair weather, the electric field in the air at a particular location immediately above the Earth's surface is 127 N/C directed downward.
Part A: What is the surface charge density on the ground?
magnitude : _____________________nC/m2
Part B: Imagine the surface charge density is uniform over the planet. What then is the charge of the whole surface of the Earth?
_______________________ kC
Part C: What is the Earth's electric potential due to this charge?
_____________________MV
Part D: What is the difference in potential between the head and the feet of a person 1.58 m tall? (Ignore any charges in the atmosphere.)
_______________________V
Part E: Imagine the Moon, with 27.3% of the radius of the Earth, had a charge 27.3% as large, with the same sign. Find the electric force the Earth would then exert on the Moon.
Magnitude :______________________N
Part F: Compare the answer to part (e) with the gravitational force the Earth exerts on the Moon.
Fgravitational /Felectric =_______________________
Please show the work for the calculation so I can understand what I'm doing. Thanks!
