Near the surface of Earth we may approximate the effects of gravity
by the weight of the two masses, according to
F1,ext
= m1 g e3
and
F2,ext
= m2 g e3
where g represents the gravitational
acceleration near the surface of Earth
and e3
the vertical unit vector.
On substitution of the above result into the
previous expression
for μa, we obtain
μa =
F12
No effects of gravity remain near the surface of Earth.
