I What are the stable orientations for a dipole in an external e-field

Click For Summary
Stable orientations for a dipole in an external electric field occur when the dipole aligns with the field direction, minimizing potential energy. If the dipole is slightly perturbed from this alignment, it experiences a restoring torque that returns it to the stable position. The stability of these orientations depends on whether the external field is uniform; in a uniform field, the dipole will return to equilibrium, while in a non-uniform field, it may move toward regions of higher field strength. The discussion emphasizes the importance of understanding the dipole's behavior in varying field conditions. Overall, the dipole's orientation and response to perturbations are crucial for applications in electrostatics.

What are the stable orientation(s) for a dipole in an external electric field? What happens if the dipole is slightly perturbed from these orientations?

Is the external field uniform?
 
Thread 'The rocket equation, one more time'
I already posted a similar thread a while ago, but this time I want to focus exclusively on one single point that is still not clear to me. I just came across this problem again in Modern Classical Mechanics by Helliwell and Sahakian. Their setup is exactly identical to the one that Taylor uses in Classical Mechanics: a rocket has mass m and velocity v at time t. At time ##t+\Delta t## it has (according to the textbooks) velocity ##v + \Delta v## and mass ##m+\Delta m##. Why not ##m -...
