Question
Why does the rider placed on the string fly off when the string and fork act in unison?
Solution
Sonometer vibrations are forced vibrations.
When the string and the fork are in unison i.e. frequency of tuning fork is equal to the frequency of string, resonance occurs and string vibrates with a larger amplitude and hence the rider flies off.
