Question

A circular parallel-plate capacitor is formed of two closelyspaced disks. The electric field strength in the space between theplates is 1.0 x 105 N/C as a result of transferring 3.9x 109 electrons from one disk to the other. What is thediameter of the disk?

Explanation / Answer

the electric field between the plates of acapacitor                E = V / d the capacitence of a capacitor                     C = Q / V            V = Ed = Q /C       and C = A/d              Ed = dQ / A               A = Q / E              r^2 =  Q / E               r = Q / E .            diameter of the plate           D = 2r = 2(Q / E ).      Q = 3.9 x 109 * 1.6 *10^-19 Col        E = electric fieldbetween the plates          Q = 3.9 x 109 * 1.6 *10^-19 Col        E = electric fieldbetween the plates
