If the magnitude of the electric field in air exceeds roughly 3 x 106 N/C, the air breaks down and a spark forms. For a two-disk capacitor of radius 51 cm with a gap of 4 mm, what is the maximum charge (plus and minus) that can be placed on the disks without a spark forming (which would permit charge to flow from one disk to the other)? The constant eo = 8.85 x 1012 c2/(N•m²).
