Two identical elastic springs PQ and QR have a natural length L and modulus of elasticity 2mg. The springs are joined together at Q. Their other ends , P and R , are attached to fixed points , with P being 4L vertically above R. A particle of mass m is attached at Q and hangs at rest in equilibrium. Find the distance of the particle below P.
So i managed to solve this question assuming QR was stretched at start , but lets say PQ is stretched at start ,it didnt work with me , am i doing it wrong or does that mean QR was actually stretched at first? Thanks
