#30N#

Explanation:

The tension in the strings provide the necessary centripetal force.
Now, centripetal force #F_c=(m*v^2)/r#
Here, #m=20kg#, #v=3ms^-1#, #r=3m#
So #F_c=60N#
But this force is divided between two ropes.
So the force on each rope is #F_c/2# i.e #30N#
This force is the maximum tension.
