Questions
A stretched string of 1m length and mass is having tension of 20N. If it is plucked at 25cm from one end then it will vibrate with frequency
detailed solution
Correct option is B
As we know plucking distance from one end =l2p⇒25=1002p⇒p=2. Hence frequency of vibration n=p2lTm=22×1205×10−4=200Hz.Talk to our academic expert!
