I understand that if I were to put a Nikon FD 100mm lens on a Nikon crop sensor camera such as a D7100 the ' effective ' focal length would be 150mm.
My question is what would be the ' effective ' focal length of a Nikon FX lens of that same crop sensor camera ?
Thanks,

Yes, x 1.5.
Note, however, that your aperture will also be multiplied by 1.5 so you are losing a great deal of light.
