A second order nonlinear ode in an electrostatics problem

  1. Feb 27, 2013 #1
    I encountered the following second order nonlinear ODE while solving a problem in electrostatics. The ODE is: [itex]\frac{d^{2}V}{dx^{2}} = CV^{-1/2}[/itex]

    How can I solve this?

    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution

    Normally, the Forum requires some attempt at a solution before help is given. In this case, either you have seen the trick or you haven't. So, I hope I'm not violating policy by going ahead and giving you a hint. Try multiplying both sides by 2 dV/dx.
