Study of a spherical inhomogeneous distribution - Corrected Exercises Gauss Theorem


Considering in the vacuum a sphere of radius R, the center O, with a volume charge distribution :



and k are constants and


1. Determine the expression of the electrostatic field at any P in space. Note OP = r.
2. Show that within the sphere, the electrostatic field has a maximum for a ratio r / R given.



Calculate the value of k in the case where the field is extremum for r / R = 1/2

Solution : Hydrogen atom - Corrected Exericises on Gauss - electromagnetism

∎ Back to the exercise Hydrogen atom. 1. electrostatic field. As the vector electrostatic field is opposite the gradient of the potential V and it depends only on r (the distribution having spherically symmetrical) are obtained: 2. Feed field. The flow of the electrostatic field is defined by: As the field's radial component and constant over a sphere of radius r: The study gives limits: to r tends to 0 Φ = 0   for r approaching infinity. According to Gauss, a domestic load sphere of radius r expressed as: . We can therefore conclude that the total charge distribution is zero and that at point O we have a positive point charge q. 3. Volumetric charge density. The charge contained between the spheres with center O and radius r and r + d r is: Is then obtained: This charge density is negative and has a total charge...

INVASION OF THE SKY - MACHINES

Image
FROM the day when man began to assert his superiority over other animals he began to cast longing eyes at the sky. Fired with ambition and stirred with a spirit of mastery he chafed at the bonds that bound him to earth; but the heavens remained a forbidden kingdom to him. Many a bold adventurer who dared to emulate the birds paid the penalty of his temerity with a broken limb and even with his life. It seemed as if man were destined forever to grovel on the bed of the atmospheric ocean with never a chance to rise except in dreams and fancy. It was not until near the close of the eighteenth century that a means of rising off the earth was discovered. Two brothers, Stephen and Joseph Montgolfier, of Annonay, France, were sitting before a fire, watching the smoke curl up the chimney, when it occurred to one of them that smoke might serve as a vehicle to carry them up into the air. They belonged to a prominent paper-manufacturing family and naturally turned to that materia...
