Given that the distance between the Earth and the Moon is d = 3.84 x 10^8 m, show
that a satellite located exactly in-between the Earth and the Moon at a distance of
90% d from the Earth experiences no net force (at least when only the
gravitational force due to the Earth and the Moon at taken into account). Draw a
diagram showing the forces acting on the satellite.

Ok, draw a diagram. The force from Earth minus the Force from the Moon adds to zero if it is no net force.

ForceEarth-ForceMoon=?
GMeMs/(.9)^2 - GMmMs/(.1d)^2=?

Me/.81 - Mm/.01=?

can you do that?
