Two short magnets each of moment M are placed one over the other at right angles. The resultant magnetic induction at a point ‘P’, that lies at  distance ‘d’ from the common centre is $\sqrt{\mathrm{p}}\frac{{\mathrm{\mu }}_0}{4\mathrm{\pi }}\frac{\mathrm{M}}{{\mathrm{d}}^3}$ then ‘p’ is (P lies in the plane of the figure)
