Homework Statement
There is a point on the line between the centres of the Earth and the moon where their gravitational fields have equal magnitude but are in opposite directions, effectively creating a point of zero gravity. Calculate the distance of this point from the centre of the earth.
gearth = 9.81 ms[itex]^{}-2[/itex]
mearth = 6.02 x10[itex]^{}24[/itex] kg
Homework Equations
F = GMm/d[itex]^{}2[/itex]
g = -GM/d[itex]^{}2[/itex]
The Attempt at a Solution
Using ratio of the inverse square laws Rm[itex]^{}2[/itex]/Re[itex]^{}2[/itex] = Mm/Me
Using F = 0 and gearth = gmoon
