ir
r
where
c
is
a
constant
and
r
is
the
distance
from
the
origin;

ir points out from the origin.
What is the difference in the value of the electric potential
due to this electric field between the point x=a, y=b and
the point at infinity?
What is the potential function corresponding to this
electric field if instead of being at the origin the source
of the electric field is at point x=a, y=b?
