  6) both about the same for the same altitudes.

Question 2

Escape speed from Earth is about
 
  1) 8 km/s.
  2) 11.2 km/s.
  3) more than 11.2 km/s.
 
  Interestingly, if a stone released at rest at the far edge of the solar system drops to Earth by virtue of only Earth gravity, it will strike Earth's surface with a speed of about
  4) 8 m/s.
  5) 10 km/s.
  6) 11.2 km/s.
