Here , $tan\theta$ $<$ $co-efficient$ $of$ $friction$ .

Hence , the body will not slide and the string will be slack.

So , Tension in the string will be zero.

$T=0$

Sin theta?

No its $tan\theta$ !!!!! Here we are dealing with the Angle of Friction which is the angle between the resultant of the force of limiting friction $f$ and the normal reaction $R$ .

Hence , $tan\theta$ $=$ $f/R$ $=$ $co-efficient$ $of$ $friction$ .

But here $tan\theta$ $<$ $co-efficient$ $of$ $friction$ .

Hence $T=0$ .
