Question

give the derivation of Newton's Inverse Square rule...


(Pls don't be brief..... Give step by step explanations) ​

Answer 1

Formula[edit]

Mathematically notated (see ∝):  

intensity   ∝   1 /distance^{2}

It can also be mathematically expressed as:  

intensity 1/ intensity 2 =(( distance_{2}^{2}}{{distance}}_{1}^{2}}}  

or as the formulation of a constant quantity:  

{\text{intensity}}_{1} {{distance}}_{1}^{2}={{intensity}}_{2} {\text{distance}}_{2}^{2}}  

The divergence of a vector field which is the resultant of radial inverse-square law fields with respect to one or more sources is everywhere proportional to the strength of the local sources, and hence zero outside sources. Newton's law of universal gravitation follows an inverse-square law, as do the effects of electric, magnetic, light, sound, and radiation phenomena.
