A current I 10 A flows in a ring of radius ro 15cm made of a very thin wire The tensile strength of the wire is equal to T 1 5N The ring is placed in a magnetic field field which is perpendicular to the plane of the ring so that the forces tend to break the ring The magnetic field in T at which the ring is broken is
