Two parallel, coaxial circular disks 1 and 2, each of area 21.8 cm^2, are separated by a small distance 0.8 mm. The disks 1 and 2 are charged uniformly with charge -4 nC and 1 nC, respectively. How much work is required for an external force to move a proton located between and far from the edges of the disks very slowly from a point very close to disk 1 to one very close to disk 2?
