Force due to gravity = GMm/r^2
here
F1=force on moon due to earth
F2=force on earth due to moon
M=mass of earth
m=mass of moon
R=distance between earth and moon
according to equation,
F1/F2 =(GMm/r^2)/(GMn/r^2)
therefore
F1/F2=1
hence F1=F2

F1=force on moon due to earth
F2=force on earth due to moon
