Question

A spring constant (k) is cut into (n) equal parts.the force constant of each part will be what ?

Answer 1

we know, spring force , F = -Kx here K is spring constant and x is elongation or compression of spring.
Here you should remember when a spring cuts then you should take F remains constant . Then , $\bold{K\propto\frac{1}{x}}$
Means if you cut spring of spring constant K into n parts then spring constant will be nK .

Hence, spring constant of each part will be nK

Answer 2

Nk where n is number of parts and k is constant force
