Ques1. The quality factor of tuning fork is 104. Calculate the time interval, after which its energy becomes 1/10 of its initial value. The frequency of tunig fork is 250Hz.
Ques2. An under damped harmonic oscillation has its amplitude reduced to 1/10thof its initial value after 100 oscillations. If its time period is 1.15s then calculate (i)damping constant (ii) relaxation time
