Question
What is the escape velocity (Unit 18 ) from the surface of a $1-M_{\odot}$ white dwarf that has a radius of $10^{4} \mathrm{km}$ ?
Step 1
First, we need to find the mass of the white dwarf. We are given that it has a mass of $1-M_{\odot}$, which means it has the same mass as the Sun. The mass of the Sun is approximately $1.989 \times 10^{30} \mathrm{kg}$. Show more…
