Question

A schwarzschild black hole is characterized by its mass M and a mathematical spherical surface of radius $R_s=\frac{2GM}{C^2}$ called the event horizon. If the radial distance of an objec r from the black hole is such that $r<R_s,$ then the object is "swallowed " by the black hole and r rapidly decreased to the singular point $r=0.$ Find the minimum energy $E_{min,}$ in $\text{MeV}$, required to dissociate this BHP atom from the ground state.

Answer 1

$r_B=\frac{h^2}{GM{m}^2}M<2\times {10}^{11}kg.E_{min}=55MeV$
