Two beams, A and B, of plane polarised light with mutually perpendicular planes of polarisation are seen through a Polaroid. From the position when the beam A has maximum intensity (and beam B has zero intensity), a rotation of Polaroid through 30 makes the two beams appear equally bright. If the initial intensities of the two beams are respectively, then equals
