Find the fundamental note emitted by a string of length `10sqrt(10)` cm under tension of 3.14 kg. Radius of string is 0.55 mm and density `=9.8gcm^(-3)`.

Text Solution

Verified by Experts

Here, `l=10sqrt(10)cm=0.1m,`
`T=3.14kg=3.14xx9.8N`
`D=2r=2xx0.5mm=1mm=0.001m,`
`rho=9.8g//c c=9.8xx10^(3)kg//m^(3)`
As, `v=(1)/(lD)sqrt((T)/(pirho))`
`:.v=(1)/(0.1sqrt(10)xx0.001)xxsqrt((3.14xx9.8)/(3.14xx9.8xxx10^(3)))`
