Two short magnets of magnetic moments 0.8 Am2 and 2.7 Am2 are placed along the same straight line with their like poles towards each other. The distance between their centers is 40cm. The distance of the neutral point on their common axial line from the center of the stronger magnet is

a
16cm from strong magnet
b
24cm from strong magnet.
c
20cm between the magnets, 60cm outside the magnets.
d
