Question

what is the mathematical equation of a black hole

Answer 1

Answer:

F = E/r: In this equation, the gravitational force at the boundary of a black-hole is equal to the Planck-force, 'F' . The value of (E/r) remains constant for all black-holes (since the Planck-force, 'F , is a constant).

Answer 2

there is no such equation...

but i can tell you why light can't escape black hole.....

its because ..if we analise the formula

[2GM/R]^1/2

the mass is almost equal to infinite and radius is almost equal to 0 then the ratio becomes very capable to catch light

M≈infinte

R≈0

Hope it helps..
