Answer: (c) any two bodies having some mass . I've tried googling, but haven't found good answers. In modern language, the law states: Every point mass attracts every single other point mass by a force pointing along the line intersecting both points. The law of universal gravitation states that any two objects in the universe attract each other with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. 1.
