Hi,
An object with the largest size will have a large gravitational force acting on it. Explanation
The gravitation force increases with increase in size of an object. An object that has twice as much mass will exert two times as much gravitational pull on other objects. An object with greater mass attracts the earth more strongly that the other one with smaller mass. On the earth’s space, the more massive objects will exert stronger gravitational forces.
Best wishes!
