PHYS208 Fundamentals of Physics II
Hint for Ch. 23, 34P
Span the rod with a variable x.
I chose x=0 at the end closest to P so that integration was from 0 to -L.
The contribution to the electric field from each infinitesimal element charge
points to the right. Check the far-field limit for point-charge behavior.
