Question
A block of mass ‘m’ is pulled by a uniform chain of mass ‘m’ tied to it by applying a force F at the other end of the chain. The tension at a point which is at a distance of quarter of the length of the chain from the free end will be...
The correct answer is:
Tension in the chain at the final end of full length is F = (m+m)a
Tension in the chain at quarter length from free end,
