Newtons law of gravitation

  1. Sep 30, 2009 #1
    1. The problem statement, all variables and given/known data

    Which of the following statements about Newton’s Universal Law of Gravity is false?

    A. The heavier mass exerts a force on the lighter mass that is equal but opposite to the force the lighter mass exerts on the heavier mass.
    B. A heavy mass from far away can exert the same gravitational force on you as a light mass that is nearby.
    C. Masses under the influence of the gravitational force accelerate towards each other at the rate of 6.67 x 10-11 m/s2.
    D. All of the above are true.



    2. Relevant equations
    F=[tex] 6.673(10)\ \times\ 10^{-11}\ m^{3} kg^{-1} s^{-2}[/tex]*([tex]_{}M1[/tex][tex]_{}M2[/tex])/[tex]\frac{}{}r^{}2[/tex]


    3. The attempt at a solution
    The heavier mass could exert a force equal dependent on distance from the second mass.

    Hi jake40208, welcome to PF.
    The gravitational force is a mutual attractive force between two bodies.
    Both will attract each other with equal magnitude of forces.
