Hi; Could somebody please help me with the following question: Dry air will break down and generate a spark if the electric field exceeds about 2.90E+6 N/C. How much charge could be packed onto a green pea (diameter 0.800 cm) before the pea spontaneously discharges?
The formula i used was E=kq/r^2. And the answer i got was 5.0E-9 C. But that answer is not correct, does anyone know what I am doing wrong? Thanks.
