I was solving a static electricity/electric field problem and I came across with one saying Earth has an electric field of roughly 150 N/C at the surface. The book also states that it's negative, direction is toward the center of Earth's core.
So from the equation of F=qE one can find easily the necessary charge needed to counter effect the gravity:
mg=qE
so for a 187 pond man the charge must be something like 5.5 C. I assume that means if "somehow" I could charge my body 5.5C negative, that would balance my weight and I could levitate.
Is that correct? Is something missing with this picture?
