Two short magnets with pole strengths of 100 ab ampere-cm and 64 ab ampere-cm are placed with their axes in the sarme vertical line, with similar poles facing each other, Each magnet has a length of 1 cm. When separation between the nearer poles is 1 cm, the weight of upper magnet is supported by the repulsive force between the magnets. If g= 1000" cm/s"^(2), then the mass of upper magnet is

1.	Two short magnets with pole strengths of 100 ab ampere-cm and 64 ab ampere-cm are placed with their axes in the sarme vertical line, with similar poles facing each other, Each magnet has a length of 1 cm. When separation between the nearer poles is 1 cm, the weight of upper magnet is supported by the repulsive force between the magnets. If g= 1000" cm/s"^(2), then the mass of upper magnet is
