The block is placed on a frictionless surface in gravity free space. A heavy string of a mass m is conncected and force `F` is applied on the string then the tension at the middle of rope is
.

Options

A. `(((m)/(2)+M).F)/(m+M)`
B. `(((M)/(2)+m).F)/(m+M)`
C. zero
D. `(M.F)/(m+M)`

Answer

A

Explanation

`F =ma, a = (F)/(M+m), T =((m)/(2) +M)a`
