Given,
The mass attached to the spring, m=2 kg
The spring constant of the spring to which the mass is attached, k=200 N/m
The time of the oscillation of the oscillator is given by,
The frequency is related to the period of the oscillator as,
Thus the frequency of the oscillator is given by,
On substituting the known values in the above equation,
Thus the frequency of oscillation of thus formed oscillator is 1.59 Hz
