Given the radii of two wires is of the ratio 2:1.
Using the formula as per Hooke's law,
i) When both the wires are under the same stress, strain produced will be the same.
ii) When both the wires are loaded by the same weight, then
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.
Inter-atomic or inter-molecular forces are electrostatic in nature.
