That's what I thought, I need more information to be able to draw a conclusion. V is the escape velocity, g universal gravitational constant, d density and R the radius. I

I mean in general. If a planet have a slightly faster escape velocity and is bigger than another planet. What can we say about the density of this bigger planet with a faster escape velocity? Is the density for this planet larger or lower compared to the planet that is smaller and have a less...

I can see when I have the same density and only change radius R to a larger value, I get a larger value for escape velocity. Maybe it is hard to draw a conclusions from this as we do not know if the density is the same...

I do not really understand ,as we do not know if they have the same density

V= sqrt ((2*G*M)/(R)) And M is volume * density. Then the density have to be lager, for the bigger planet with a greater escape velocity?

Hi! I have a question about escape velocity. If a planet is bigger and have a greater escape velocity than another planet. Do this effect the density of the bigger planet in any way? Or do we have to know the mass of the bigger planet to know if the density is larger or lower for this planet?
