WebSolution: We know that the work required to take a unit mass from P to infinity = −V p, where −V p is the gravitational potential at P due to the disc. To find V p, we divide the disc into small elements, each of thickness dr. Consider one such element at a distance r from the center of the disc as shown. Mass of the element dm= π(4R) 2− ...

WebThe Gravitational Field of a Disk. Morgan, Thomas. ; Morgan, Lesley. The general solution of the static field equations of general relativity is given for a disk of "counterrotating" dust particles. The only nonvanishing components of the energy-momentum tensor are T00 and Tχχ, which are assumed to have δ-function singularities on the disk. WebA gravitational field that falls off more slowly than the classical Newtonian field accounts for not only the M-sigma effect, it accounts for the anomalous velocity dispersion and all the other phenomena associated with Dark Matter.
