Question

A spring has an unstretched length of 12 cm . It exerts a restoring force F when stretched to a length of 13 cm . At what compressed length is the restoring force 2F ?

Answer 1

10 cm

Step-by-step explanation:

1 cm of stretch = F

so 2 cm of compression from equilibrium = 2F this would be 12 - 2 = 10 cm
