A disc of mass m ,radius R is shown rolling on horz surface(having sufficient friction).
Variation of magnetic fields with direction exist along its path as shown in figure
CHARGE ON DISC=Q
1)Find velocity of disc after very long time
2)predict if it will roll at that instant.
3)Predict the plane in which it will be travelling at that instant
4)Calculate 1,2,3 for x=R/128
