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 force constant of ___________ Correct Answer (3/2) k

Force constant, k = F/x The length of the long piece is 2x/3 So, its force constant is k‘=F/(2x/3)=3F/2x=3/2×k.
