MattO ---regarding your ?????
 

The escape velocity at the surface of the earth is approximately 8 km/s. What is the excape velocity for a planet whose radius is 4 times and whose mass is 100 times that of earth?



Escape velocity is defined to be the minimum velocity an object must have in order to escape the gravitational field of the EARTH, that is, escape the EARTH without ever falling back.


Does this planet have the same gravitational field?? I want to answer this question but I can not with the facts you have stated!
