In which scenario will the two objects have the greatest gravitational forcebetween them?A. Mass of object 1 = 12 kgMass of object 2 = 12 kgDistance between objects = 1.5 mO B. Mass of object 1 = 15 kgMass of object 2 = 12 kgDistance between objects = 1.5 mC. Mass of object 1 = 15 kgMass of object 2 = 12 kgDistance between objects = 0.5 mD. Mass of object 1 = 12 kgMass of object 2 = 12 kgDistance between objects = 0.5 m

An object slides along a curved track of negligible friction, as shown in the figure. The potential energy U of the object as a function of the position x is shown in the graph. The object starts at rest at x=0. Which of the following is a correct claim about the motion of the object?(Would prefer an explanation, but it's not necessary)A) The kinetic energy of the object is approximately the same at x=2m and x=5m.B) At x=2m, the object has more potential energy than kinetic energy.C) The object comes to rest when x=5.5m.D) The rate of change of the potential energy is a minimum at x=0m.E) The object achieves its maximum speed at approximately x=3m.
