Two Spheres m1 and m2 if mass 85.8kg and 102.7kg, respectively,exert the gravitational force of 6.78 x 10^-11N to each other. how far apart are their center in meters?

Answer 1

Work with the equation

F = Gm₁m₂ / r²

Solve for r and get

r = √(Gm₁m₂ / F)

Look up G in your physics book. You were given m₁, m₂, and F. Plug in the numbers and finish from here.
