Question

Gravitational force between two point masses m and M
separated by a distance is F. Now if a point mass 2m is
placed next to m in contact with it, the force on M due to m
and the total force on M are:
:​

Answer 1

Answer:

Now if a point mass 2m is placed next to m is contact with it. The force on M due to m and the total force on M are. On M due to m force is F and due to mass 2m force is 2F. Therefore, net force is 3F.

Answer 2

Answer:

Now if a point mass 2m is placed next to m is contact with it. The force on M due to m and the total force on M are. On M due to m force is F and due to mass 2m force is 2F. Therefore, net force is 3F.

                                                    OR

Gravitational force will remain same on mass M and gets no effect by the presence of any mass. Hence, the force on M due to m is F.

∴Total force=F+2F=3F

The force are F and 2F.
