Answer:
Explanation:
Given:
length of unstrained spring,
mass attached to the spring,
length of the spring after hanging the mass,
energy to be stored in the spring,
<u>The length of the spring stretched after hanging the mass:</u>
<u>Therefore the stiffness constant of the spring:</u>
where
F = is the force to which the spring is subjected for the corresponding change in length .
here,
<u>As we know that the spring potential energy is given as:</u>
where
extension in the length of the spring
<u>So the total length of the spring when it stores 10 J energy:</u>
