a string of length l and mass m hangs freely from a fixed point
calculate the velocity of the transverse wave at any position
sol:
mass per unit length is m/l
let there be a point on the string at a distance x from free end
tension at the point=wt of the string per unit length*part of the string
=(m/l)*x*g
and sol continues.
my doubt is why isn't the upper part contributing to the tension?
weight due to upper part must be pushing down the lower part.
