What condtions u need for zero gravity state?

[nadavg54]

i read that if u r in "spaceship" that's for example has circular orbit around Earth - than u r in a zero gravity state.
but from Newton law u get this equations :
mMG/R^2-N=mV^2/R

so from this i get that N equal MG/R^2-V^2/R
and why would MG/R^2-V^2/R be zero ? no metter what?
