A string of length 2m and mass 2 gmn is stretched by a certain tension so that it vibrates in 4 segments with a frequency of 600 Hz. What is the tension ?

Text Solution

Verified by Experts

The correct Answer is:
p-number of segments `mu=2 xx 10^(-3)//2=10^(-3) kgm^(-1). T=4pil^2mulp^2=4 xx 600^2 xx 4 xx 10^(-3)//16=360N`
