I've got a question in front of me that asks to find the escape velocity for a hypothetical celestial object that has the same density as the sun.
MC answers are -
1)2.51 x 10^3 m/s
2)6.18 x 10^5 m/s
3)3.08 x 10^5 m/s
4)5.42 x 10^10 m/s
As far as I can work out its not possible to find an escape velocity while only knowing the density. I can work out that
v = 8.873 x 10^-4 x r
but not find actual v without knowing the radius.
