Do you mean like in a situation where the dipole is hold at an arbitrary angle from the field and then released?gracy said:What if a dipole is slightly displaced from it's unstable equilibrium position ,will it execute angular SHM?
I mean if the dipole initially makes 180 degrees with electric field and then it is displaced from there will it execute SHM?blue_leaf77 said:Do you mean like in a situation where the dipole is hold at an arbitrary angle from the field?
That example is also included in the situation I described above.gracy said:I mean if the dipole initially makes 180 degrees with electric field and then it is displaced from there will it execute SHM?

You mean it won't execute SHM?gracy said:I mean if the dipole initially makes 180 degrees with electric field and then it is displaced from there will it execute SHM?
What does your trained intuition tell you? Try to trust yourself if you know your reasoning can be supported by the known physics formula.gracy said:In this case motion of dipole is combination of translatory and rotatory motion .
Right?
If the displacement from stable equilibrium is small enough you can model the motion as a SHO. This is valid for any system, not restricted to dipole in a specific type of field.blue_leaf77 said:What does your trained intuition tell you?

Right. For many potential functions, particularly in the case of one dimensional motion, a small displacement from a stable equilibrium position results in SHM, Simple Harmonic Motion.nasu said:If the displacement from stable equilibrium is small enough you can model the motion as a SHO.

Even in non uniform electric field?SammyS said:a small displacement from a stable equilibrium position results in SHM, Simple Harmonic Motion.
What is the potential function in this case?gracy said:Even in non uniform electric field?

where p is the dipole moment and E is the electric field.I don't know about potential.
I did.gracy said:Please answer my post #13 .
A dipole in an electric field refers to a system where two opposite charges of equal magnitude are separated by a distance. This creates a dipole moment, which is the measure of the strength and direction of the dipole.
The stability of a dipole in an electric field depends on the orientation of the dipole moment with respect to the electric field. If the dipole moment is aligned with the electric field, it is in a stable equilibrium. However, if the dipole moment is perpendicular to the electric field, it is in an unstable equilibrium.
Simple harmonic motion is a type of oscillatory motion where the restoring force is directly proportional to the displacement from the equilibrium position. In the case of a dipole in an electric field, the restoring force is provided by the electric field, causing the dipole to oscillate back and forth in a regular pattern.
The strength of the electric field affects the SHM of a dipole by determining the frequency of the oscillations. A stronger electric field will result in higher frequency oscillations, while a weaker electric field will result in lower frequency oscillations.
Yes, the oscillations of a dipole in an electric field can be damped by external forces such as friction or resistance. This will result in a decrease in the amplitude of the oscillations over time, eventually causing the dipole to come to a rest at its stable equilibrium position.
