Question: Consider a spring that stretches 4cm when a load of 10 N is suspended from it. How much with the spring stretch if an identical spring also supports the load? (Neglect the weights of the springs.)
Okay, so I am assuming that k is constant. [ k = F/x ]
F = 10 N, x = 4 cm, x = 2.5 N/cm
10 points to first and best answer!

Each spring bears half the load, so each spring will have a force of 5 N with a spring constant of 250 N/m.
x = F / k
x = 5 / 250 = 0.02 m = 2 cm.
x = F / k
x = 5 / 250 = 0.02 m = 2 cm.
