I Derive equation of mechanical equilibrium

  1. Jan 29, 2017 #1
    Derive equation of mechanical equilibrium for a (non rotating and in equilibrium) with a shell of radius r and depth dr.

    This equation should relate the gradient of pressure and gravitational force.

    Relevant equations:

    dP/dz = - ρg
    F = GMm/r^2
