Gravity around a Black Hole

The actual gravity of such a black hole is,

$g=-\cfrac{{G}_{o}}{(x+{r}_{eo})^2}$

${g}_{eo}=-\cfrac{{G}_{o}}{{r}_{eo}^2}$ = -3.980484e14/(0.00886)^2 = -5.07071e18 ms^-2

And the corresponding gravity equation is,

$g=-{g}_{eo}{e}^{-\cfrac{{g}_{eo}{r}_{eo}}{{G}_{o}}(x)}=-{g}_{eo}{e}^{-\cfrac{1}{{r}_{eo}}(x)}$

$g$ = -(5.07071e18)*e^(-112.86690*x)

This graph of g = -(5.07071*10^18)*e^(-112.86690*x) has been scaled in the x-axis by $\cfrac{1}{1000}$ and in the y-axis by $10^{14}$.  But it is still possible to calculate from the formula ${x}_{e}$ when $g={g}_{o}$ around a black hole.

9.80665 = (5.07071*10^18)*e^(-112.86690*$x_e$)

${x}_{e}$ =  ln((5.07071*10^18)/9.80665)/112.86690 = 0.3613 m.
