A mass m is vertically suspended from a spring of negligible mass; the system oscillates with a frequency n. What will be the frequency of the system, if a mass 4m is suspended from the same spring?
(a) n/2
(b) 4n
(c) n/4
(d) 2n
I had been asked this question at a job interview.
My question is taken from Oscillations in chapter Oscillations of Engineering Physics I
