A chain of mass per unit length `lambda` and length 1.5 m rests on a fixed smooth sphere of radius `R = (2)/(pi) m` such that A end of chain is at the top of sphere while the other end is hanging freely. Chain is held stationary by a horizontal thread PA. The tension in the thread is:

A unifrom flexible chain of length 3/2 m rests on a fixed smooth sphere of radius R= 2/pi m such that one end A of chain is on the top of the sphere while the other end B is hanging freely. Chain is helpd stationary by a horizontal thread PA as shown . Calculate the acceleration of chain when the horizontal string PA is burnt ( g = 10 m//s^(2))

A chain of length l and mass m lies on the surface of a smooth sphere of radius R>l with one end tied to the top of the sphere.

A chain of length l and mass m lies of the surface of a smooth hemisphere of radius Rgtl with one end tied to the top of the hemisphere. Taking base of the hemisphere as reference line, find the gravitational potential energy of the chain.

A chain of length l and mass m lies of the surface of a smooth hemisphere of radius Rgtl with one end tied to the top of the hemisphere. Taking base of the hemisphere as reference line, find the gravitational potential energy of the chain.

A chain of length 1 and mass m lies on the surface of a smooth sphere of radius Rgt1 with one end tied to the top of the space. Find the gravitational energy of the chain with reference level at the centre of the sphere

A chain of length l is placed on a smooth spherical surface of radius R with one of its ends fixed at the top of the sphere. What will be the acceleration of the each element of the chain when its upper end is released? It is assumed that the length of the chain l<((piR)/2) .

A chain of mass m and length L is held at rest on smooth horizontal surface such that a part I of the chain is hanging vertically from the table. If the chain is let go, what is its speed as its end just leaves the horizontal surface?
