Question:

Two metal spheres are separated by a distance of 1.0 cm and a power supply maintains a constant potential difference of 900 V between them. The spheres are brought closer to one another until a spark flies between them. If the dielectric strength of dry air is 3.0 × 106 V/m, what is the distance between the spheres at this time?
