Suppose the the earth were made only of protons, but had the same surface size and mass it presently has. What would be the acceleration of an electron released at the surface? Disregard gravitation force.
The Attempt at a Solution
I solved for the number of protons and got something like 3.57 X 1051
Since that would be multipled by the charge of the proton, I just squared my charges and set the above number as "n." Solved for "a." My number was something times 1073 but my friend got something times 1090
Do either of these sound correct?
