    Homogeneous Second Order O.D.E Problem Please help

    you will eventually get A=120 and B=200. just sub those conditions into v(r)=A+B/r separately and solve A and B simultaneously

    is there any other way to simplify the exponential before applying the conditions?

    Homogeneous Second Order O.D.E Problem Please help

    i found the general solution to be v(r)=A+Be^(-r). then, what's next?
