Hello, I have a question on finding out electric force a dipole exerts on a test point charge.
So if you have a dipole sitting at a y-axis, distance s apart,
what would be the force the dipole exert on the test charge that lies in the x-axis
-----------------------------------------------------------------------------------------------------------------
q-
q(t)
q+
----------------------------------------------------------------------------------------------
And what if the q(t) was moved to y-axis
----------------------------------------------------------------------------------------
q(t)
q-
q+
The answer for this one is
(2 K q q(t) s r) / (r^2 -(s/2)^2)^2
I am not sure how you get that answer …
please show all works and thanks for your time.

An electric dipole consists of a negative charge- located at (0,-) and a positive charge +q located at (0, +3). The dipole moment p is defined as a vector of magnitude qs directed from the negative charge of the dipole to the positive charge of the dipole.

An electric field can induce an electric dipole in a neutral molecule (or atom) by pushing the positive and negative charges inside the molecule in opposite directions. The dipole moment of the induced dipole is directly proportional to the electric field at the molecule. That is, p⃗ =αE⃗ , where p⃗ is the induced dipole moment, α is called the polarizability of the molecule, and E⃗ is the electric field at the molecule. A stronger electric field at the molecule results in a...
Torque on a Dipole in a Uniform Field (Looking for explanation, not just answers)
Consider an electric dipole whose dipole moment (a vector pointing from the negitive charge to the positive charge) is oriented at angle with respect to the y axis. There is an externalelectric field of magnitude (independent of the field produced bythe dipole) pointing in the positive y direction. The positive and negative ends of the dipole have charges and , respectively, and the two charges are a distance apart. The dipole has a moment of inertia about its center of...

2. Dipole-dipole force The charge distribution where two equal but opposite charges are separated by a fixed distance a dipole and is very common and important in nature. Consider two dipoles, each consisting of charges ±q separated by a distance δ. The axes of two dipoles are parallel and their midpoints are separated by a distance r. One is inverted compared to the other. See the figure tq +9 (a) Calculate the force exerted on each dipole by the other...

An electric dipole is formed from two charges, ±q, spaced a distance s apart. The distance s is small compared to 10 cm. The dipole is at the origin, and the dipole moment p⃗ points in the y-direction. The electric field strength at the point P:(x,y)=(0cm,10cm) is 320 N/C 1. The two charges, ±q, are spaced a distance s apart. The dipole moment p⃗ is rotated 90∘ so it points in the +x-direction. What is the electric field E⃗ at the point P:(x,y)=(0cm,10cm) ? Give your...

A dipole is made of a rod of length d with charge +q on one end and −q on the other. You place it lying along the y-axis with its center at y >> d, so the +q charge is at (0, y + d/2, 0) and the −q charge is at (0, y − d/2, 0). A test charge of magnitude +Q is placed at the origin. Find a simple (monomial) approximate expression for the magnitude of the net...
