Step-by-step explanation:
Hooke's Law applies here, which is a linear relationship. It would be easier to solve this using proportions with N of force on the top and the amount of stretch in cm on the bottom. Set up with our unknown, the number of cm:
and cross multiply:
20x = 300 so
x = 15 cm
The answer is f because it equals 1/3 and f is 1/3
answer is C 1/4
see attached picture, it is not exact but with rounding it comes out correct.
