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

Answer»

`(((m)/(2)+M).F)/(m+M)`
`(((M)/(2)+m).F)/(m+M)`
ZERO
`(M.F)/(m+M)`

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