Thank you.

Do not post code as an image. Put in the actual code or a notebook.
Please read the rules of the forum: http://wolfr.am/READ-1ST

The derivative of a function is not written as F[R]', but as either F'[R] or D[F[R],R].

You do not have to specify $$ F1[R]=c1 F1[R]+C2 F2[R] $$ Just use

DSolve[eqn,F1[R],R]

Your definition for eqn already has the ==0
