1. The problem statement, all variables and given/known data View attachment ECE_220_Matlab_Problem_1.pdf 2. Relevant equations E = (q(R-R')) / (4*pi*epsilon*|R-R'|^3) 3. The attempt at a solution Ignore the matlab part of the problem .. i can do that easily. I just need a head start ... so should i first calculate the E between the specified set of points and each of the 10 charges, then average it out to get the avg E for the first set? or should i find the average R between the 10 charges ( i can use that value for all 3 sets of coords) then subrtact R' (the set of coords) from it then etc? Thanks for the help.
