Dear shivanshi

Let the force F is aplied on the link and it is moving with and acceleration a.

and  chain has total 1 link

F- n*1*g =na

a= F/n -g


let N1 force is applied by link 2 on link 1

 N1- 1*g = 1*a

N1 = g+a


let N2 force is applied by link 3 an link 2

N2 -2*g =2*a

 N2 = 2(g+a)


similerly other link
