Question

Determine the required radius for the Sun to become a Black Hole. Write the name for the radius

Answer 1

Given:

The mass of the sun is

`M_(sun)=1.989*10^(30)\text{ kg}`

The universal gravitational constant is

`G\text{ = 6.67}*10^(-11)\text{ Nm}^2\text{ /kg}^2`

The speed is

`c=\text{ 3}*10^8\text{ m/s}`

To find the required radius for the sun to become a black hole.

Step-by-step explanation:

The radius can be calculated as

`\begin{gathered} r=(2GM)/(c^2) \\ =(2*6.67*10^(-11)*1.989*10^(30))/((3*10^8)^2) \\ =2948\text{ m} \end{gathered}`

The name of the radius is Schwarzschild radius.
