Question
A $1.00-\mathrm{km}$ length of power line carries a total charge of $264 \mathrm{mC}$ distributed uniformly over its length. Find the magnitude of the electric field $54.3 \mathrm{~cm}$ from the axis of the power line, and not near either end (staying away from the ends means you can approximate the field as that of an infinitely long wire).
Step 1
The length of the power line is given as $1.00 \, \mathrm{km}$, which is equal to $1000 \, \mathrm{m}$. The distance from the axis of the power line is given as $54.3 \, \mathrm{cm}$, which is equal to $0.543 \, \mathrm{m}$. Show more…

A $10-\mathrm{cm}$ long rod carries a charge of $+50 \mu \mathrm{C}$ distributed uniformly along its length. Find the magnitude of the electric field at a point $10 \mathrm{~cm}$ from both the ends of the rod.
A charged line like that shown in Fig. 21.24 extends from $y=2.50 \mathrm{cm}$ to $y=-2.50 \mathrm{cm} .$ The total charge distributed uniformly along the line is $-7.00 \mathrm{nC}$ . (a) Find the electric field (magnitude and direction) on the $x$ -axis at $x=10.0 \mathrm{cm} .$ (b) Is the magnitude of the electric field you calculated in part (a) larger or smaller than the electric field 10.0 $\mathrm{cm}$ from a point charge that has the same total charge as this finite line of charge? In terms of the approximation used to derive $E=Q / 4 \pi \epsilon_{0} x^{2}$ for a point charge from Eq. $(21.9)$ , explain why this is so. (c) At what distance $x$ does the result for the finite line of charge differ by 1.0$\%$ from that for the point charge?
The magnitude of the electric field at a point $x$ meters from the midpoint of a 0.1 -m line of charge is given by $E(x)=\frac{4.35}{x \sqrt{x^{2}+0.01}}(\text { in units of newtons per coulomb, } \mathrm{N} / \mathrm{C}).$ Evaluate $\lim _{x \rightarrow 10} E(x).$
