A thin, long rod of length 13.0 m lies along the x axis with its center at the origin. The total charge on the rod is
−155 µC.
(a) What is the net electric field at the location
(0, 34.5 m)?
(Express your answer in vector form.)
Erod
=
N/C
(b) To see how the value of the electric field changes if
y ≫ L,
determine the net electric field at the location
(0, 345 m).
(Express your answer in vector form.)
Erod
=
N/C
