If (d^(2)y)/(dt^(2))+4=0 is the difference equation of SHM then period

1.	If (d^(2)y)/(dt^(2))+4=0 is the difference equation of SHM then period of oscillation is………second.
Answer» Solution :Comparing EQUATION `(d^(2)y)/(dt^(2))+4y=0` with general DIFFERENTIAL equation `(d^(2)y)/(dt^(2))+omega^(2)x=0` `omega^(2)= 4` `THEREFORE omega =2` `therefore (2PI)/(T)= 2` `therefore T= pi s` `therefore T= 3.14 s`.
