In the figure shown above,
A and B are two objects of mass
and
.
A third object C of mass
m
is lying in between A and B.
is
the angle of two intersecting tangents of A
and C,
is the angle of two intersecting tangents of
C and B.
Force of attraction between
A and C = K
m
Force of attraction between
C and B = K
m
If C is lying at the
neutral space we get
K
m
= K
