Expert Answer
Let us assume axial direction of bar magnet is along x-axis and equtorial direction is along y-axis

Axial direction magnetic field at a distance x = ( μo / 4Π ) [ (2M) / x3 ]

Equtorial direction magnetic field at a distance y = ( μo / 4Π ) [ M / y3 ]

If both the magnetic fields are equal, then we have , [ 2 / x3 ] = [ 1 / y3

Hence , we get ,  ( y / x ) = ( 1 / 21/3 )  = 2 -1/3
