An object has a mass of 0.25 kg what is the gravitational force of on the object by the earth?

"Weight" = (mass) x (acceleration of gravity)

               = (0.25 kg) x (9.8 m/s²)

               =        2.45 newtons        (about  8.8 ounces of force).

-- The Earth pulls on the object with 2.45 newtons of force.
    (The object weighs 2.45 newtons on Earth.)

-- The object pulls on the Earth with  2.45 newtons of force.
    (The Earth weighs 2.45 newtons on the object.)

A) acceleration. this seems to be the one that makes sense.
