## Question:

An unstretched hanging spring is 50 cm long. Suspending a 100 N weight from it makes its length 60 cm. Adding another 100 N weight will make the spring:

a) 60 cm

b) 70 cm

c) 80 cm

d) 100 cm

e) 120 cm.

## Hooke's Law:

According to Hooke's law, the change in length of the spring due to the tensile or compressive load applied on the spring is directly proportional to the magnitude of the load applied on the spring. Mathematically,

{eq}\Longrightarrow \rm F=Kx {/eq}

Where;

• {eq}\rm K {/eq} be the spring constant
• {eq}\rm x {/eq} be the change in length of the spring
