The correct answer is:
$S>E>W>G$
We know that, among all inverse forces based on inverse square law's gravitational force is the weakest and nuclear force is the strongest.
Hence, $F_{\text {Strongnuclear }}>E_{\text {Electromagnetic }}>F_{\text {Gravitational }}$ $\ldots(\mathrm{i})$
Weak nuclear force is a fundamental force in nature that underlies some forms of radioactivity, governs the decay of unstable subatomic particles such as meson and initiates the nuclear fusion reaction that fuels the sun.
These forces are considered weaker than electromagnetic forces and stronger than gravitational forces, i.e.
$F_{\text {Electromagnetic }}>F_{\text {Weak nuclear }}>F_{\text {Gravitational }}$ $\ldots(\mathrm{ii})$
Given, $\quad F_{\text {Electromagnetic }}=E \Rightarrow F_{\text {Strongnuclear }}=S$
$F_{\text {Weak nuclear }}=W$ and $F_{\text {Gravitational }}=G$
Using Eqs. (i) and (ii), we get
$S>E>W>G$
Hence, $F_{\text {Strongnuclear }}>E_{\text {Electromagnetic }}>F_{\text {Gravitational }}$ $\ldots(\mathrm{i})$
