Please answer all parts in legible handwriting, Thank you. A rod of length
L
(see the figure) lies along the
x
axis with its left end at the origin. It has a nonuniform charge density
\lambda =
\alpha x
, where
\alpha
is a positive constant. (a) What are the units of
\alpha
? (b) Calculate the electric potential at
A
. (c) Calculate the electric potential at
B
.
