Which of the following different equations represents a damped harmoni

1.	Which of the following different equations represents a damped harmonic oscillator ?
Answer» `(d^(2)y)/(DT^(2))+y=0` `(d^(2)y)/(dt^(2))+gammady)/(dt)+y=0` `(d^(2)y)/(dt^(2))+K^(2)y=0` `(DY)/(dt)+y=0` SOLUTION :`(d^(2)y)/(dt^(2))+(gammady)/(dt)+y=0`
