spring constant of spring of length L is K....
now k is inversly proportional to length ..
so , K2/K1 = L1/L2
from here we can compare force constant of two different lengths of wire of same material..
let force constant of each half is k1 after cutting then
k1/k = L/(L/2)
k1 = 2k
both of these parts are connected parallel so net force constant = 2k+2k=4k
approve my ans if u like it
