    At what distance does a charge attain half its speed at infinity?

    Yes. The initial velocity of the free charge is 0, since it's released from rest. The equation for the potential of a point charge is V = kq/r. I feel like I am making this more difficult than it needs to be, like I am missing something very simple just in terms of how I'm thinking about...

    At what distance does a charge attain half its speed at infinity?

    Homework Statement A charge of 3.40μC is held fixed at the origin. A second charge of 3.40μC is released from rest at the position (1.25m, 0.570m). If the mass of the second charge is 2.49 m, and its speed at infinity is 7.79 m/s, at what distance from the origin does the second charge attain...
