n indentical blocks each of mass m are connected by means less strings and a pulling force F is applied on the first block. Find block . Find the tension in the string connecting `k^("th")` and ) `(k+1)^("th")` blocks. If another pulling force F is applied on the least block, find the tension in the same . String.

Options

A. `[F(n-k)//n]N,F`
B. `[F(n-k)//n]N,nF`
C. `[F(n+k)//n]N,F`
D. `[2F(n-k)n]N,F`

Answer

A
