Balls weighing 1 kg each hang motionless on three springs.The initial lengths of the springs are the same. The oscillation period of which of the pendulums will be the longest? Why?

The period of oscillation of a spring pendulum depends on the properties of the spring: the greater the elongation of the spring under the influence of the weight of the same load, the longer the period of oscillation.
