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 c about an axis passing through the centre of mas and perpendicular to its plane If the net magneti field at the centre of the disc is 0 then the rati m is 1 1 2 40 M MOTIKU MOTCACE 2 2 1
