Question

n indentical blocks each of mass m are connected by means of mass less strings and a pulling for
F is applied on the first block. Find the tension in the string connecting k and )(k+1) blocks.
another pulling force F is applied on the last block, find the tension in the same string.
F(-kn]N.F 2) [F(n-k/n]N.OF 3) F(n+k/n]NF 4) [2F(n-k)/n]NF​

Answer 1

Answer:

n Identical blocks each of mass m are connected by means of mass less strings and a pulling force F is applied on the first block. Then the tension in the string connecting k and (k+1) block is given

by

TK,K+1=F×(n−k)/n

If another pulling force F is applied on the last block, the tension in the same string is

TK,K+1 =F
