An elastic material has a length of 36\ \mathrm{cm} when a load of 40\ \mathrm{N} is hung on it...

Question:

An elastic material has a length of {eq}36\ \mathrm{cm} {/eq} when a load of {eq}40\ \mathrm{N} {/eq} is hung on it and a length of {eq}45\ \mathrm{cm} {/eq} when a load of {eq}60\ \mathrm{N} {/eq} is hung on it. Find the original length of spring.

Restoring Force:

Restoring force of a spring is the force exerted by the spring in order to oppose the action force which is applied in order to compress or stretch the spring and the restoring force is dependent on the spring constant and the displacement of the spring from its initial position.
