# A second order nonlinear ode in an electrostatics problem

I encountered the following second order nonlinear ODE while solving a problem in electrostatics. The ODE is: $\frac{d^{2}V}{dx^{2}} = CV^{-1/2}$

How can I solve this?

Regards.

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.
