Answer:
Explanation:
Expression for velocity of wave produced in a hanging wire can be given as follows
Velocity v = [tex]\sqrt{\frac{T}{m} }[/tex]
where T is tension in wire and m is mass of wire per unit length.
In the given case
T = Mg + mg
= Mg
neglecting weight of rope
mass of the rope per unit length
= m / L
Velocity of wave
= [tex]\sqrt{\frac{Mg}{\frac{m}{L} } }[/tex]
= [tex]\sqrt{\frac{MgL}{m} }[/tex]
