A ring of radius `R` is made of a thin wire of material of density `rho` having cross section area `a.` The ring rotates with angular velocity `omega` about an axis passing through its centre and perpendicular to the plane. If we consider a small element of the ring,it rotates in a circle. The required centripetal force is provided by the component of tensions on the element towards the centre. A small element of length `dl` of angular width `d theta` is shown in the figure.

If for a given mass of the ring and angular velocity, the radius `R` of the ring is increased to `2R`, the new tension will be
