A square loop of area 25cm2 has a resistance of 10Ω. The loop is placed in uniform magnetic field of magnitude 40.0 T. The plane of loop is perpendicular to the magnetic field. The work done in pulling the loop out of the magnetic field slowly and uniformly in 1.0 sec, will be
(1) 2.5 × 10-3 J
(2) 1.0 × 10-3 J
(3) 1.0 × 10-4 J
(4) 5 × 10-3 J
