One end of a wire 1m long is fixed at the centre of rotating horizontal table and other end is attached to 2kg load. Find the increase in the length of wire when table rotates with angular velocity 2.5 rad/s. The radius of wire is 2 x 10–4 m and Young's modulus of the material of wire 1.8 x1010 N/m2.

Given,

Length of one end of wire, L = 1m

Therefore tension in the string is,

Increase in the length of the wire = (5.53 - 1) = 4.53 m

What is the force of adhesion?

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.
