Why should an electron falling into the nucleus, according to the Maxwell's laws of electrodynamics, destroy the atom?
It is often said in physics and chemistry classes and textbooks that atoms must be unstable when the electron continuously loses energy and finally fall into the nucleus according to classical physics....

Radiation from accelerated charged in a co-accelerated reference frame
I was wondering if I sit on a accelerated charge particle I will not observe radiation since the particle is at rest according to me. But my friend observes it from outside and he will see radiation ...

Paradox in the observation of ripple
What I am going to speak about may not be a paradox but i see a contradiction here so I used used the word "paradox". To begin with, let there be 2 charges A and B which are stationary with ...

Accelerated Electric Charges
We know that an accelerated electric charge produces electromagnetic radiation.
We also know that acceleration is relative to an observer.
Take electrically neutral observers A and B, who are ...

Which equations indeed describe moving/accelerated charge field?
The thing that I have not understood completely, for 100%, is how does the field of the electric charge is "updated".
If to consider a frame of reference where the charge is static, does ...

Why would an orbiting electron lose energy?
Ernest Rutherford proposed that the electrons were orbiting around the nucleus just like planets orbiting around the sun. However, this simple picture defied the laws of physics. Electrons revolving ...

Why do accelerating electrons emit radiation?
I know how you can emit light with an alternating current, running back and forth, creating an electric field in addition to the magnetic field.
But why does an electron emit light when it gets ...

Does a rotating ring of charge radiate power or not?
The Larmor Formula suggests that the power radiated by an accelerating charge is non zero. But we know that a uniformly charged non-conducting ring rotating about its central axis does not radiate. ...

How and why do accelerating charges radiate electromagnetic radiation?
Let's consider it case by case:
Case 1: Charged particle is at rest. It has an electric field around it. No problem. That is its property.
Case 2: Charged particle started moving (it's accelerating)....

Energy-work theorem and dissipation of energy by an accelerating charge
By the work energy theorem we have that the total energy of a nonrelativistic point charge, $q_0$ of mass $m$, moving in an electric field $\mathbf{E}$ is
$ E = E_k + U_e = \frac{1}{2}mv^2 + q_0V \...

Why does an accelerated charge radiate away energy?
My textbook says:
"Neils Bohr objected to the idea of an electron orbiting a nucleus in a circular orbit. An electron experiences centripetal acceleration and an accelerated charge radiates away ...

Does a constantly accelerating charged particle emit EM radiation or not?
The Abraham-Lorentz force gives the recoil force, $\mathbf{F_{rad}}$, back on a charged particle $q$ when it emits electromagnetic radiation. It is given by:
$$\mathbf{F_{rad}} = \frac{q^2}{6\pi \...
