Solution

  1. Statement:
    Every particle of matter attracts every other particle of matter with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
  2. In vector form, it can be expressed as,
    `vec"F"_21 = "G" ("m"_1"m"_2)/"r"^2(- hat"r"_21)`
    where, `hat"r"_21` is the unit vector from m1 to m2. The force `vec"F"_21` is directed from m2 to m1.
Concept: Universal Law of Gravitation
