Tom’s mass is 70.0 kg, and Sam’s
mass is 50.0 kg. Tom and Sam are
standing 20.0 m apart on the dance
floor. Sam looks up and sees Tom.
Sam feels an attraction. Supposing
that the attraction is gravitational,
find its size. Assume that both Tom
and Sam can be replaced by
spherical masses.
5.84Å~10−10 N
Question
Answer:
5.84×10^-10 N
Explanation:
F=G×ms×mr/r^2
ms=50 kg
mr= 70 kg
r=20 m
F=6.67×10^-11 N×m^2/kg^2×50 kg×70 kg/(20 m)^2
F=5.84×10^-10 N
