Two short bar magnets with pole strengths of 900 ab amp x cm and 100 ab amp x cm are placed with their axes in the same vertical lines with similar poles facing each other Each magnet has a length of 1 cm When the separation between the nearer poles is 1cm The weight of the upper magnet is supported by the repulsive force between the magnets If g is 100 cm sec then the mass of the upper magnet is A 100 g B 55 g C 77 5 g D 45 g
