Question
34 In Fig. 23-45, a small circular hole of radius R = 1.80 cm has
been cut in the middle of an infinite, flat, nonconducting surface
that has uniform charge density o= 4.50 pC/m?. A z axis, with its
origin at the hole's center, is perpendicular to the surface. In unit-
vector notation, what is the electric field at point Pat z = 2.56 cm?
Hint: See Eq. 22-26 and use superposition.)
