Spherical mass distribution
http://hyperphysics.phy-astr.gsu.edu/hbase/Mechanics/Keporb.html WebThis calculation is made possible by the fact that the orbiting mass experiences a net attraction only by that mass inside its orbit, and the mass outside its orbit exerts a net zero force. Upon calculating the circular orbit velocity, we find that inside the spherical mass distribution, the orbit velocity increases with radius, reaching a ...

WebCharge Distribution with Spherical Symmetry A charge distribution has spherical symmetry if the density of charge depends only on the distance from a point in space and not on the direction. In other words, if you rotate the system, it doesn’t look different. WebIn the case of a spherically symmetric mass distribution we can conclude (by using a spherical Gaussian surface) that the field strength at a distance r from the center is inward with a magnitude of G / r2 times only the total mass within a smaller distance than r. All the mass at a greater distance than r from the center has no resultant effect.
