Figure 23-45 shows a
very large nonconducting
sheet that has a uniform
surface charge density
of \( \sigma=-2.00 \mu \mathrm{C}^{2} \); it
also shows a particle of
charge \( Q=8.00 \mu \mathrm{C} \), at
distance \( d \) from the sheet.
Both are fixed in place. If
\( d=0.200 \mathrm{~m} \), at what (a) positive and (b) negative coordi-
nate on the \( x \) axis (other than infinity) is the net electric
field \( \vec{E}_{\text {net }} \) of the sheet and particle zero? (c) If \( d=0.950 \mathrm{~m} \),
at what coordinate on the \( x \) axis is \( \vec{E}_{\text {net }}=0 \) ?
