Question

two planets of masses "m" and "M" respectively. have a center to center separation of "R".At what distance from the center of the planet of mass"M" do the gravitational force of planets cancel each other?????
help me plzzz??????

Answer 1

G•m(o)•M/x^2 = G•m(o)•m/(R-x)^2,
m/M = (R-x)^2/x^2,
Since all numbers are positive,
sqrt(m/M) = (R/x) -1.
x = R/[1 +sqrt(m/M)]
