3 Positive like charge of linear charge density is passed on the outer circumference of an annular disc having outer radius 2R Negative like charge of linear charge density 2 is passed on the inner circumference of the disc having inner radius R The disc is rotating with constant angular velocity w about an axis passing through the centre of mass wills and perpendicular to its plane If the net magnetic field at the centre of the disc is 0 then the ratio 1 is X Lo ni o exsh xxx x x x
