If the total mass hanging on one end of the string that creates the tension in the string is 0.300 kg, what is the mass density (mass per unit length) μ of the string?

The mass density of the string is (0.3/L) kg/m

Explanation:

Mass density of the string = Mass/Length

Mass = 0.3kg

The length of the string is unknown so it is assumed to be L meter (s)

Therefore, mass deny of the string = 0.3kg/Lm = (0.3/L) kg/m
