JEE 2022 on Gravitational Self-Energy
Gravitation self-energy of a uniform sphere Let us evaluate the gravitational self-energy of a uniform solid sphere of mass M and radius R. Since we are now considering continuous mass distribution, the summation goes over to integrals. The calculation is stated below as following:
Self-energy
In chemistry, the self-energy or Born energy of an ion is the energy associated with the field of the ion itself. [citation needed]In solid state and condensed-matter physics self-energies and a myriad of related quasiparticle properties are calculated by Green''s function methods and Green''s function (many-body theory) of interacting low-energy excitations on the basis of electronic
Determine the electrostatic self energy of a uniformly charged solid
Hint: Firstly, we will have to find the charge element and its relation with the volume charge density of the sphere. Thereafter, we will find the work element produced from the charge element for a very small radius. Assuming that the sphere is made up of ample of such charge elements, we will integrate the work done element and obtain the electrostatic self energy of the sphere.

No headers (text{FIGURE V.24A}) The potential outside a solid sphere is just the same as if all the mass were concentrated at a point in the centre. This is so, even if the density is not uniform, and long as it is spherically distributed. We are going to find the potential at a point (text{P}) inside a uniform sphere of radius (a), mass (M), density (ρ), at a distance (r) from
