Question
7) Find the force of gravity between two 74.0 kg physics students that are sitting 0.85 m apart
7579.24 N
5.057 x 10(-7) N
None of these choices are correct
9.8 x 10(-7) N
I'm unsure of how to begin.

F= m1m2/d^2
F= 74*74/(0.85)^2
F= 5476/0.7225
F= 7579.24 N
F= 74*74/(0.85)^2
F= 5476/0.7225
F= 7579.24 N

You left out the universal constant of gravity, G, which is a very small number. Look it up and apply it.
F= G*m1*m2/d^2
F= G*m1*m2/d^2
