A polarizer - analyser set is adjusted such that the intensity of light coming out of the analyser is just $\displaystyle 10 \%$ of the original intensity. Assuming that the polarizer - analyser set does not absorb any light, the angle by which the analyser need to be rotated further to reduce the output intensity to be zero, is :
