A block of mass m, when attached to a uniform ideal spring with force constant k and free length L executes SHM. The spring is then cut in two pieces, one with free length nL and other with free length (1-n)L. The block is also divided in the same fraction. The smaller part of the block attached to longer part of the spring executes SHM with frequency f1. The bigger part of the block attached to smaller part of the spring executes SHM with frequency f2. The ratio f1f2 is
