The dipole is at the origin, oriented along the x-axis. What is the electric field strength at the point
\Step 1:

The dipole is at the origin and oriented along the
-axis, and so the point
along the axis of dipole.
The electric field is
.


.
The electric field strength at
is
.
Step 2:
\The dipole is at the origin and oriented along the
-axis, and so the point
is perpendicular to to the dipole.
The electric field is
.


.
The electric field strength at
is
.
Solution:
\The electric field strength at
is
.
The electric field strength at
is
.
along the axis of dipole.
