`1` meter long metallic wire is broken  into two unequal parts `P and Q P` part of the wire in uniformly extended into another wire `R`. Length of `R` is twice  the length of `P` and the resistance of `R`  is equal to that of `Q`. Find the ratio of the resistance `P` and `R` and also the ratio of the length `P and Q`
