Physics - Electrostatics Question with Solution | TestHub

A ring of radius R is made out of a thin wire of area of cross section A . The ring has a uniform charge Q distributed on it. A charge ${\mathrm{q}}_0$ is placed at the centre of the ring. If Y is the young's modulus for the material of the ring and $\Delta \mathrm{R}$ is the change in the radius of the ring then :-
