The given question is illustrated in the figure. below.
From right angled ,
The different forces acting on mass are:
(i) Weight mg in vertically downward direction.
(ii) Tension T in the string along AS.
Now resolving the components of T as shown in fig. above.
The component Tcosθ balances the weight mg of the mass and component Tsinθ provides the necessary centripetal force to whirl the mass.
Adhesive force is the attractive force between two unlike molecules. They are caused by forces acting between two substances like electrostatic force (attraction due to opposing charges), mechanical force etc.
E.g., Force of attraction between gum and paper.
