## Question:

A spiral spring extends from length 10.01 m to 10.00 cm when a force of 20 N is applied to it. Calculate the constant force.

## Hooke's law:

When the spring are elongated or compressed from their natural length it experiences a a restoring force which is given by Hooke's law.

{eq}F = Kx {/eq}

where,

• {eq}K {/eq} is called the spring constant and
• {eq}x {/eq} is the elongation or compression of the spring.

Given:

• Initial length of the spiral spring is {eq}L = 10.01 \ m {/eq}
• The length of the spiral spring after extention is {eq}l_1 = 10.00 \ cm =...
