Homework Help: Motion of particle if gravitational charge-mass ratio is changed

  1. Mar 3, 2013 #1
    1. The problem statement, all variables and given/known data
    Two particles are falling in a lab frame. The charge to mass ratio of particle one is held at 1, while the charge to mass ratio of particle 2 is changed from 1 to 0.5. How does the motion of the second particle changed with respect to the first. Would this change cause particle 2 to interact with the gravitational field resulting in faster acceleration or slower acceleration?

    Charge of what? Gravitational charge? In Newtonian mechanics, this would change the acceleration. In General Relativity, this is not possible, gravitational charge and mass are always proportional to each other.
