Question

Spring constant of a spring is k = 6x10³ N/m. Calculate the work done to stretch it by 1 cm.
Easy

Solution

Spring constant k = 6×10³ N/m x=1cm=0.01 m Work done in stretching the spring = acquired potential energy = 1/2 kx² = 1/2 x 6 x 10³N/m x (0.01m)² = 0.3 J Therefore 0.3J work will have to be done to stretch the sprign by I cm.
