A tuning fork of 200Hz is in unioson with sonometer wire. If percentag increase in tension of wire is 1,then percentage change in frequency is???
Frequency increases by 0.49875%
Assuming fundamental modes of vibration, frequency of a string is gicven by:
T= string tension,
m= mass of string
L= length of string
So basically if m and L are constant
If T changes from 1 to 1.01 ( 1% inccease)
F increase by
That is a 0.49875% increase.
