The beams A and B of plane polarized light with mutually perpendicular planes of polarization 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 IA and IA IB respectively then equals
