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
