Homework Statement
If a proton is considered a uniform ball of charge of radius 1.0x10-15m, what is the
electric field just beyond its surface?
Homework Equations
Gauss's law?
The Attempt at a Solution
I followed a problem in the book that found an equation for the electric field of a uniformly charged sphere. I treated the proton as a uniform sphere of charge, so that the same equation could be applied.
The equation was E = (1/4piE0)(Q/r^2)
*E0 is constant 8.85 x 10^-12.
So I just plugged in charge of electron and radius r of the proton.
