CBSEENPH11016621

A uniform rope of length L resting on frictionless horizontal surface is pulled at one end by a force F. What is the tension in the rope at a distance ℓ from the end where the force is applied?

Solution
Length of the rope = L 
Linera mass density of rope = λ
Total mass of rope M = λL.
The acceleration produced by force F in the string is, straight a equals straight F divided by λL
              

Let 'T' be tension in the string at given point B which is equal to force required to pull the part AB of the string.
