Two springs A and B with same spring constant 'k' are compressed to different lengths x metres and 3x metres respectively. The forces developed in A and B are in the ratio:
1:3
Force in spring = −k x ( minus represents force is always opposite to displacement of spring)
Force in spring 'A' = −k x
Force in spring 'B' = −3 k x
Force in 'A' : Force in 'B' = 1:3
