Newton's LawEasyQuestion 30701

Question

Newton's law of gravitation states that the force between two point masses m₁ and m₂ separated by distance r is:
  1. A
    F = Gm₁m₂r
  2. B
    F = Gm₁m₂/r
  3. C
    F = Gm₁m₂/r²
    Correct
  4. D
    F = G(m₁+m₂)/r²

Correct answer

F = Gm₁m₂/r²

Explanation

F = Gm₁m₂/r², where G = 6.674×10⁻¹¹ N·m²/kg² is the universal gravitational constant. Force is attractive and acts along the line joining the masses.
