A stretched string is in unison with a tuning fork of frequency 392Hz. If the length of the string is decreased by 2% , then the number of beats heard per second will be

Text Solution

Verified by Experts

The correct Answer is:

`(Deltan)/(n) = (Deltal)/(l_2) therefore (Deltan)/(392)= 2/98 therefore Deltan=8`
