Question

A spring of force constant K is cut into two pieces such that one piece is double the length of the other.Then the long piece will have a For


ce constant of

Answer 1

If the length of the original spring was l, the lengths of the resultant springs are 2l/3, l/3.

Using the law k*l = constant, we get:

k * l = k' * (2l/3)

=> k' = 3k/2 or 1.5k
