Assuming the xylem tissues through which water rises from root to the branches in a tree to be of uniform cross-section find the maximum radius of xylem tube in a `10m` high coconut tree so that water can rise to the top.
(Surface tension of water`=0.1(N)/(m)`, Angle of contact of water with xylem tube`=60^@`)
