Problem

Three ideal springs, P, Q, and R, each experience a horizontal pulling force that produces the extensions listed below: • Spring P:

4\,\text{N}

produces a

1.0\,\text{cm}

extension. • Spring Q:

6\,\text{N}

produces a

2.0\,\text{cm}

extension. • Spring R:

5\,\text{N}

produces a

0.50\,\text{cm}

extension. Rank the springs by stiffness constant

k

, from greatest to least. a)

Q > P > R

R > P > Q

Q > R > P

P > Q > R
