24OMG its so simple...
Since resistance of body is zero ,,so infinite value of current passes through it
=> magnetic force on it is so high that it will leave contact with groud and fly ...
am i rite ??
A disc of mass m ,radius R is shown rolling on horz surface(having sufficient friction).
Variation of magnetic and electric fields with direction exist along its path as shown in figure
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
