A spring has spring constant k = 200 N/m. How much work does it take to stetch the sprin
from 10 cm to 20 cm from equilibrium ?

A spring has spring constant k = 200 N//m . How much work does it take to stetch the spring 10 cm from equilibrium ?

An extension of 10 cm is produced in a spring (spring constant = 1000 Nm^(-1) ). Calculate the work done to increase the extension from 10 cm to 20 cm.

A spring of force constant 800 N/m has an extension of 5 cm. The work done in extending it from 5 cm to 15 cm is:

A spring of force constant 800 N/m has an extension of 5 cm . The work done in extending it from 5 cm to 15 cm is

A spring of force constant 800 N/m has an extension of 5 cm. The workdone in extending it from 5 cm to 15 cm is :

A spring of force constant 800N/m has an extension of 5cm. The work done in extending it from 5cm to 15cm is

A spring of force constant 800N//m has an extension of 5cm. The work done in extending it from 5cm to 15cm is
