Is the length of two strings equall. And is there any constraint about the direction of pulling.
If the lengths are equall and end is pulled downwards then an extension of dx will produce extensions of dx*cos(theta/2) in each string.
So the net force is resultant of k1*dx*cos(theta/2) and k2*dx*cos(theta/2) with an angle of theta between them.
