Classical instability of the H-atom: In the Bohr Model of the H-atom, an electron orbits the nucleus in a circle of radius r0. One serious problem with this model is that a charged particle moving in a circle is accelerating, and an accelerating charge radiates away EM energy according to the Larmor formula (Griffiths 11.70). So the H-atom will lose energy and the electron will quickly spiral into the nucleus, according to classical electrodynamics and mechanics. (a) Derive a formula for the total energy [U(r)

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
