## Radius of Sphere of Influence( Black Hole) Solution

STEP 0: Pre-Calculation Summary
Formula Used
Sphere of Influence Radius = [G.]*(Black Hole Mass)/(Stellar Velocity Dispersion of the Host Bulge)^2
rh = [G.]*(Mbh)/(σ)^2
This formula uses 1 Constants, 2 Variables
Constants Used
[G.] - Gravitational constant Value Taken As 6.67408E-11 * Meter³/Kiogram Second²
Variables Used
Black Hole Mass - Black Hole Mass is expressed in solar mass is the mass of a particular black hole in evaluation. (Measured in Solar Mass)
Stellar Velocity Dispersion of the Host Bulge - Stellar Velocity Dispersion of the Host Bulge is the statistical dispersion of velocities about the mean velocity for a group of astronomical objects. (Measured in Kilometer per Second)
STEP 1: Convert Input(s) to Base Unit
Black Hole Mass: 4 Solar Mass --> 7.952E+30 Kilogram (Check conversion here)
Stellar Velocity Dispersion of the Host Bulge: 1000 Kilometer per Second --> 1000000 Meter per Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
rh = [G.]*(Mbh)/(σ)^2 --> [G.]*(7.952E+30)/(1000000)^2
Evaluating ... ...
rh = 530722841.6
STEP 3: Convert Result to Output's Unit
530722841.6 Meter -->530722.8416 Kilometer (Check conversion here)
530722.8416 Kilometer <-- Sphere of Influence Radius
(Calculation completed in 00.016 seconds)

### Radius of Sphere of Influence( Black Hole) Formula

Sphere of Influence Radius = [G.]*(Black Hole Mass)/(Stellar Velocity Dispersion of the Host Bulge)^2
rh = [G.]*(Mbh)/(σ)^2

## If the black body is rotating, how does it effect radius of influence?

If the black hole is rotating, there will be a second radius of influence associated with the rotation.
