Two point masses M and 3M are placed at adistance L apart. Another point mass m is placed inbetween on the line joining them so that the netgravitational force acting on it due to masses M and3M is zero. The magnitude of gravitational forceacting due to mass M on mass m will be |

Answer» letGMm = K , a be the distance between M and m . K/ a^2 = 3K / ( L- a) ^2. √3a = ( L- a) a (1 + √3) = L a = L / ( 1+ √3) K/ a^2 =K ( 1+ √3)^2/ L^2 = GMm(1+√3)/L^2 |
