A point particle with charge $Q=+4\mathrm{.}5C$ is fixed in place at

the origin. A line of charge with length $L=2\mathrm{.}0m$ and linear

charge density $=-7\mathrm{.}0n\frac{C}{m}$ is placed along the $x-$axis, with

its left end a distance $d=12cm$ from the origin. What is the

force $F$ that the line of charge exerts on the point particle?

For the limit check, investigate what happens to $F$ if the line

of charge becomes very short $($i$.$e$.,L0)$ while everything $.$

else remains fixed.
