Question

the distance of between A and B is d and the masses are M and m. then find the F ​

Answer 1

Answer:

. If r is the distance between two point masses m and M, then the gravitational force on m due to mass M is F = GMm/r2. Since the gravitational force between two point masses is independent of the presence of other masses, so if a point mass 3m is placed next to m, the force on M due to m is F=r2GMm

b. Total force on the body of mass M is F, i.e., 

F=r2GM×(m+3m)=r24GMm=4F
