Question

You have two disks, 1 and 2, both of radius R = 26.0 mm and both made of the same nonconducting material. Disk 1 carries a uniformly distributed charge q1 = 1.60μC, and the uniformly distributed charge q2 on disk 2 is unknown. You place disk 1 at z1 = 0 and disk 2 at z2 = 32.0 mm such that the symmetry axis of each disk coincides with the z axis. Using a small charged pith ball, you locate one position on the z axis where the electric force exerted on the pith ball is zero; this position is zE=0 = +88.0 mm.

What is the charge on disk
