A star is modeled as a uniform spherical distribution of matter. How gravitational pressure
\( \mathrm{P} \) on surface depends on volume of the star?

W.
(1) \( P \propto \dot{V} \)
(2) \( \mathrm{P} \propto \mathrm{V}^{-1 / 3} \)
(3) \( \mathrm{P} \propto \mathrm{V}^{-2 / 3} \)
(4) \( P \propto V^{-4 / 3} \)
