A spiral spring extend from a length of 100cm to 10.01cm when a Force of 20Nus applied on it calculate the Force constant of the spring

The total length of a spring when a mass of 20g is hung from its end is 14cm, while it's total length is 16cm when a mass of 30g is hung from the end calculate the unstreched length of the living assuming hooke's law obeyed

A Force of 15N stretch a spring to a total length of 30cm .an additional Force of 10N stretches the spring 5cm further find the natural length of the spring
