Answer:
130m
Step-by-step explanation:
What we know:
- both tables have a mass of 29kg
- the gravitational force (F_g I'll call it) is a 4.24×10⁻¹⁰[N]
- G = 6.67×10⁻¹¹[m³/kg-s²]
- F_g = GMm/R²); where "M" and "m" are the two object's masses and "R" is the distance between them
With that information, all we need to do here is plug in the known values and then isolate "R" to find the distance between the two tables.
F_g = 4.24×10⁻¹⁰ = (6.67×10⁻¹¹)(29)(29)/R²
R = √[(6.67×10⁻¹¹)(29)(29)/4.24×10⁻¹⁰] = 132.2988...m = 130m
