The mass of a spaceship is 1000kg. It is to be launched from the earth's surface out into free space. The value of g and R (radius of earth) are `10m/s^2` and 6400 km respectively. The required energy for this work will be:

6.4 `xx` `10^11` joules

6.4`xx` `10^8` joules

6.4`xx` `10^9` joules

6.4 `xx` 10^10` joules
