1. The problem statement, all variables and given/known data Dry air will break down and generate a spark if the electric field exceeds about 3.0\times 10^6 N/C How much charge could be packed onto a green pea (diameter 0.81cm ) before the pea spontaneously discharges? 2. Relevant equations E = kQ/r^2 Q = Er^2/ k <-------this is the equation to use I believe 3. The attempt at a solution (3*106)(3.81*10-3)2/8.988*109 resulting in an answer of 4.845160214*10-9 = 5*10-9 does this look right to you guys?
