I thought I did the problem right, but I don't think I came out with the right answer! Please someone check to see if I got this problem right.
Calculate the force of gravity between Earth (mass=6.0*10^24 kg) and the moon (mass=7.4*10^22 kg). The average Earthmoon distance is 3.8*10^8 m.
The answer I got was 2.05*10^20 Newtons, but it seems like it could possibly be too big. Am I wrong?

DrBob222,
No, I think it is correct.
I have 6.673E11*7.4E22*6.0E24/(3.8E8)^{2}= your number.
