Why does the paper flies off when stem of tuning fork B is touched to

1.	Why does the paper flies off when stem of tuning fork B is touched to the box
Answer» When the STEM of tuning fork B is touched to the box, the natural frequency of vibration of wire MATCHES the frequency of tuning fork and resonance TAKES PLACE. Due to this resonance of vibration, amplitude of vibration of wire increases and the paper rider flies off.if this answer is helpful to you please mark me as a brain list
