What is the force on a 1000 kg elevator that is falling freely at the acceleration of gravity?

I found ##9800N##

The force should be its weight. This is the force (gravitational) between the Earth and the elevator...the only thing is that the Earth is too massive to "see" the effect of this force (movement) while you see the elevator speeding towards the Earth (with ##g##). So: Force##=mg=1000*9.8=9800N##
