## Question:

The length of a spring is {eq}\alpha {/eq} when a force of {eq}4\, N {/eq} is applied on it. The length is {eq}\beta {/eq} when a force of {eq}5\, N {/eq} is applied then the length of spring when {eq}9\, N {/eq} force is applied is _____.

a. {eq}5 \beta - 4 \alpha {/eq}.

b. {eq}\beta - \alpha {/eq}.

c. {eq}\alpha - \beta {/eq}.

d. {eq}9( \beta - \alpha) {/eq}.

## Spring:

Spring is a device that stores the energy after deforming the shape and regains its energy after regaining the shape of the spring. Spring is a spiral form of a wire that can be an open type or closed type.
