I need some quick physics help, Newtons law of gravitation?
two 200-kg masses are separated by a distance of 1 meter. using newtons law of gravitation, find the magnitude of the gravitational force exerted by one mass on the other.

F = Gmm/r²
G = 6.67300 × 10^-11 m3/kg s²
F = (6.67300 × 10^-11)(200)(200)/1
You can do the math.

been a while, but here goes to see if this makes sense... F= ma F = Gm1m2/r^2 Equating the 2 would imply "a" in the first equation is the acceleration of gravity and m being the mass of one object or m1 so, m1a=Gm1m2/r^2 reducing by m1 a=Gm2/r^2 If this holds true, then you can calculate the mass of the second object, so the earth for eample given we know the acceleration of gravity...
