Electric Dipole Points:20 The diagram below shows a dipole centered at the origin and along the
x
-axis. Determine an expression for the total electric field at a point A (
r
=3.8L,0
) in terms of
q
and
L
. Calculate the magnitude of the total electric field at
A
, when
q=1.40\times 10^(-7)C
and
L=37.6cm
.
