A wire stretched between the two fixed supports, is plucked exacly in the middle and then released. It executes (neglect the resistance of the medium) :
(a) resonant vibrations (b) natural vibrations
(c) damped vibrations (d) forced vibrations.
Solution :
It executes free vibrations/natural vibrations
Because the periodic vibrations of a body of constant amplitude in the absence of any
external force on it are called free vibrations/natural vibrations.
