net force will be G(810-390)(12)/2.4^2 and pointed toward the larger mass.
f1=f2
G810(12)/x^2=G390*12/(4.8-x)^2
x^2(390)=(4.8-x)^2*810
solve for x.
Two spheres of mass
M1 = 810 kg and M2 = 390 kg are placed
4.80 m apart. A particle of mass m = 12.0 kg is now placed midway between the two spheres.
(a) What is the net gravitational force on the particle due to the two spheres? N toward the sphere of M1 or M2
(b) At what position between the two spheres should the particle be placed so that the net gravitational force on the particle is zero? m from the sphere of mass M1
