Fe=G=mg
Fe=kΔl
⇒mg=kΔl
!!! (d)l=Δl !!!
[tex] \frac{mg}{k}=(d)l=>\frac{270}{100}=(d)l=>2.7=(d)l[/tex]

[tex] G_{p}=m g_{p}=49 [/tex]
[tex] G_{L}=mg_{L}=8 [/tex]
[tex] \frac{G_{P}}{G_{L}} = \frac{m g_{P}}{mg_{L}} = \frac{49}{8} =>\frac{g_{P}}{g_{L}} = \frac{49}{8}<=>\frac{9.8}{g_{L}}= \frac{49}{8}=>g_{L}=1.6[/tex]
