1.	If for damped oscillations if (k)/(m) = ((b)/(2m))^(2), then is the oscillation exist?
Answer» Solution :No, because angular frequency fo damped oscillator is `OMEGA.= SQRT((k)/(m)-(b^2)/((2M)^2))" if "(k)/(m)= ((b)/(2m))^(2)" then "omega.=0` Periodic TIME will be infinite. Oscillation does not exist.
