A constant direct current of uniform density `hatj` is flowing in an infinitely long cylindrical conductor.The conductor contains an infinitely long cylindrical cavity whose axis is parallel to that of the conductor and is a a distance `vecl` from it.What will be the magnetic induction `vecB` at a point inside the cavity at a distance `vecr` from the centre of cavity?
