What is the acceleration due to gravity on black hole?

In the case of a solar mass black hole the tidal stress (acceleration per unit length) is enormous at the horizon, on the order of 3\times10^9(M_{\rm o}/M)^2\mathrm{s}^{-2}\ : that is, a person would experience a differential gravitational field of about 10^9 Earth gravities, enough to rip apart ordinary materials.

What is the gravity of a black hole?

A black hole is a region of spacetime where gravity is so strong that nothing — no particles or even electromagnetic radiation such as light — can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

What is the value of acceleration due to gravity at equator?

Acceleration due to gravity is zero at the centre of the earth. The value of g is least at the equator and maximum at the poles. It means the value of acceleration due to gravity increases as we go from the equator to the poles.

What is the acceleration of a black hole in physics?

A Black Hole (BH) is an object of General Relativity (GR), not of Newtonian physics, so the answer involves both. First Newton: As another answer notes, the acceleration due to gravity depends on the mass of the body divided by the square of the distance from it.

How big is the event horizon of a black hole?

The biggest known black hole is about 10,000 times more massive than Milky way centre, so has an event horizon diameter of around 230 billion km and event horizon gravity is down to a mere 38 times earth gravity. That is only about 50 \% higher than the gravity on the “surface” of the sun.

What is the gravity of a black hole in the Milky Way?

A small natural black hole is about 4 times the mass of the sun and with a diameter of about 22 km has an event horizon gravity of about o.4 trillion x earth gravity (g). The black hole at the centre of the Milky Way? It has a diameter of about 25 million km which is about 17 times the diameter of the (uncompressed) sun.

What is the surface of a black hole like?

Black holes don’t have a “surface”. They are surrounded by a theoretical boundary called the “event horizon”, which works as a “point of no return”. It doesn’t have a physical manifestation, much like there is nothing marking the area of space where geostationary orbits are possible.
