Question

How to find the density(rho) of the Sonometer wire? By using which formula we can find?​

Answer 1

Answer:

Linear Mass density of Sonometer wire = Mass / Length

For mass of wire, Density × volume = Mass

If wire is cylindrical in shape, then

Volume of wire = pi ( r) ^2 h

Hence, Formula becomes, Linear mass density = rho × pi( r)^2 h / l ( for length)
