A spring whose unstretched length is 1 has a force constant \( k \). The spring is cut into two pieces of unstretched length \( l_{1} \)
\( \mathrm{P} \) and \( l_{2} \), where \( l_{1}=n l_{2} \) and \( n \) is an integer. The ratio \( k_{1} / k_{2} \) of the corresponding force constants, \( k_{1} \) and \( k_{2} \) will
