Length of one end of wire, L = 1m
Angular velocity,=12 rad/s
Mass of the load, M=2kg
Therefore tension in the string is,
Increase in the length of the wire = (5.53 - 1) = 4.53 m
Inter-atomic or inter-molecular forces are electrostatic in nature.
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.
