Two springs of force constant `100N//m` and `150N//m` are in series as shown the block is pulled by a distance of `2.5` cm to the right from equilibrium position what is the ratio of work done by the spring at left to the work done by the spring at right:

Give the expressions for work done by the spring and external pulling force.

Two springs of spring constants 1500N//m and 3000N//m respectively are streched by the same force. The potential energy gained by the two springs will be in the ratio

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

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

A force of 20.0 N is required to hold a spring stretched by 5.0 cm from its equilibrium position. How much work was done in stretching the spring ?

A block whose mass is 1 kg is fastened to a spring. The spring has a spring constant of 100N/m. the block is pulled to a distance x=10 cm from its equilibrium position at x=0 on a frictionless surface from rest at t=0. the kinetic energy and potential energy of the block when it is 5 cm away from the mean position is
