1. The problem statement, all variables and given/known data Provide a proof of Gauss’s law starting from Coulomb’s law for a point charge 2. Relevant equations F=kq1.q2/r^2 (closed)s∫E.n.da=qenc/ε0 3. The attempt at a solution My starting point is: F21=1/(4∏.ε0).(q2.q1)/r21^2.r(unit vector)21 *Note, the 21 terms after F and r should be subscripts and here's where I've ended up: E*vector*(r*vector*)=[F*vector*(r*vector*)]/q0= 1/(4∏.ε0).Ʃi(qi)/ri0^2.r(unit vector)i0 Not sure if I'm even on the right track. If anyone could provide the proof it'd be much appreciated.
