F = kx
so k = 20/10 = 2 N/cm
so F = 2x
Now just find x for various values of F.
If 30N is applied, maybe the spring will exceed its stretch limit and become unusable.
a sprig stretches by 10 cm when a force of 20 n is applied when a force of 22 n is used the s spring stretches by 11 cm
What would be the extension for forces of
10n? 1n? 15n?
Suggest what the extension of the spring might be if a force of 30 was applied.
