TSny's latest activity
-
TSny replied to the thread Falling capacitor connected to constant voltage.Your two methods look correct. I did catch a spot where you have two compensating errors: Check the signs in this calculation... -
TSny replied to the thread B Using energy principles to find equilibrium depth of floating object.Yes. Nice analogy. -
TSny reacted to sophiecentaur's post in the thread B Using energy principles to find equilibrium depth of floating object with
Like.
We're in the same neck of the woods as where there's an apparent paradox with the energy before and after a charged capacitor is... -
TSny replied to the thread Help with derivation of electric field of a moving charge.Good. If you wish, you can post your work for ##\nabla \mu## and we can review it. -
TSny replied to the thread B Using energy principles to find equilibrium depth of floating object.If you release the block from rest at the position where it starts to submerge, then the only two forces doing work as the block... -
TSny replied to the thread Conducting Sphere and Dipole Problem.Is this taken directly from your teacher's PowerPoint slides? Does it represent your teacher's solution to the problem of post #1? Are... -
TSny replied to the thread Conducting Sphere and Dipole Problem.This problem is not the same as the one given in your first post. It appears to be totally unrelated. You mention your teacher's... -
TSny replied to the thread Help with derivation of electric field of a moving charge.Besides the error pointed out by @anuttarasammyak, check your work for the following: I get an additional term proportional to... -
TSny replied to the thread Conducting Sphere and Dipole Problem.Your homework statement mentions dielectrics. But the actual problem statement does not mention dielectrics. It's not clear to me... -
TSny replied to the thread I Is Callen right in claiming dQ=TdS for all quasi-static processes?.It appears to me that Callen’s deduction of ##dQ = T dS## for quasi-static processes is essentially contained in sections 1.8 and 2.1... -
TSny reacted to Steve4Physics's post in the thread Flux through a ring due to two charges with
Like.
@palaphys, for an intuition, it helps to visualise flux lines. In the following diagram, the magnitude of the flux through the loop due... -
TSny reacted to Dale's post in the thread I Coulomb gauge implies instantaneous radial electric field? with
Like.
As was pointed out by @QuarkyMeson, no, because it is only part of the field. However, Maxwell’s equations admit causality-reversed... -
TSny reacted to QuarkyMeson's post in the thread I Coulomb gauge implies instantaneous radial electric field? with
Like.
Longitudinal electric field isn't an observable, E is. (Save some electrostatic near field stuff when E is approx ##E_{\parallel}## and...
