Hello Candidate,

The initial frequency of a damped oscillator is 250 Hertz which gets reduced to one tenth of its initial time, for 200 cycles or oscillations.

The new frequency for 200 oscillations will be 1/10× 200= 20 Hertz. So, frequency for one oxidation is equal to 1/200×20= 1/10 Hz. So, the new time period for oscillation is equal to 10 seconds.

Hope it helps!!
