Two short bar magnets have magnetic moments 1.20 `Am^(2)` and 1.00 `Am^(2)` respectively . They are kept on a horizontal table parallel to each other with their north poles pointing towards the south . They have a common magnetic equator and are separated by a distance of 20.0 cm.
The value of the resultant horizontal magnetic induction the mid point O of the line joining their centers is (Horizontal components of Earth's magnetic induction is `(3 xx 10^(-5) Wb m^(-2) )` ...............

A
