1. The problem statement, all variables and given/known data Find Fg if G=6.67*10-11m3 kg-1s-2, M=2.6*1023 kg, m=1200kg, and r = 2000m 2. Relevant equations Fg= -GMm/r2 3. The attempt at a solution Fg=-GMm/r2 Fg=- (6.67*10-11m3kg-1s-2)(2.6*1023 kg)(1200kg)/(2000m)2 Fg=- (6.67*10-11m3kg-1s-2)(2.6*1023 kg)(1200kg)/4000000 m2 Fg= - 2.08*1016 kg m3 s-2/4000000m2 Fg= - 5,202,600,000 mkg/s2 Fg= - 5.21*109 mkg/s2 First, I'm not sure how to deal with the units here. I added the exponents across and subtracted if they had the same unit below them but I'm not sure I ended up with the right units. Also, I don't know if you can have a negative number in scientific notation. Lastly, I don't even know if the problem was solved correctly. Thank you for any help, I'm beyond rusty at math like this.
