Weight of the load = 200 N
Elongation caused in the wire is given by,
To find - Elastic potential energy stored in the wire = ?
Therefore, energy stored in the wire is given by,
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.
