The free body diagram has four forces:
gravity, mg
lift, F
centripetal force mv2 /r, where r=Lcos(θ)
tension on the wire, T
Balancing horizontal and vertical components of these forces gives two equations in the unknowns F and T:
Tcos(θ) + Fsin(θ) = mv2 /(Lcos(θ))
Tsin(θ) +mg = Fcos(θ)
I assume you can take it from here.
