Chapter 24, Problem 005 An infinite nonconducting sheet has a surface charge density 0 12 C 2 on one side How far apart are equi tential faces whose potentials er b Number Units the tolerance is +/-9%

Solution

E = sigma / 2 e0

deltaV = E . d

52 = (sigma / 2 e0) d

52 = (0.12 x 10^-6 / (2 x 8.854 x 10^-12) ) (d )

d = 7.67 x 10^-3 m or 7.67 mm
