A circular disc `X` of radius `R` is made from an iron of thickness `t`, and another disc `Y` of radius `4R` is made from an iron plate of thickness `t//4`. Then the relation between the moment of mertia `I_(x)` and `I_(Y)` is :

A circular disc X of radius R is made from an iron plate of thickness t, and another disc Y of radius 4R is made from an iron plate of thickness (t)/(4) . Then the relation between the moment of inerita I_X and I_Y is

A circular disc X of radius R made from iron plate of thickness 't' and another disc Y of radius 4R made from an iron plate of thickness t/4 . Then the relation between the moments of inertia I_(x) and I_(Y) is

A circular disc A of radius r is made from an iron plate of thickness t and another circular disc B of radius 4r is made from an iron plate of thickness t//4 . The relation between the moments of inertia I_(A) and I_(B) is (about an axis passing through centre and perpendicular to the disc)
