More gravitational force is exerted on object B since it has higher mass. Force and mass are directly proportional so when mass is higher then the force is larger. However, when the mass is small, then the force is well small. From the statement above, object A has a mass of 25 grams which is smaller with object B with a mass of 50 grams.
