7.2.1 of Griffith's Introduction to Electrodynamics 2nd Ed
Calculating the electric field given a sphere of uniform charge with changing angular momentum. Here, we deal with quasistatics, where even though the currents are changing, we still use the magnetostatic equations.

Here you caculated E(faraday) with the help of A but that A was due to the cahrges that were rotating, but we cannot have charges at the region for applying faraday's law. Can you please explain me this doubt.

Can U explain How Did u get that E(faraday)?
