-Well assuming you have these values:
Earth Mass, MT=5.98·E 24 kg
Earth Radius, RT=6370 km= 6.37·E 6 m
Moon Mass, ML=7.34·E 22 kg
Moon Radius, RL=1740 km= 1.74·E 6 m
Distance between Earth & Moon, d=384000 km=384.0·E 6 m
Gravitation constant, G=6.67·E -11 N m2/kg2
Again, according to this values, they attract each other with a force that equals:
F = G · ( MT · ML) / d2
F = 1.9854·E 20 N

you ought to use F=G*m1*m2/r*r defined via newton yet be careful it is in simple terms valid for element hundreds. while you're calculating the gravitational between earth and moon you are able to evaluate the 2d of inertia and then attempt to calculate the gravitational tension.
