JEE Main 2023 Physics question

A thin infinite sheet charge and an infinite line charge of respective charge densities + and + are placed parallel at 5 m distance from each other. Points 'P' and 'Q' are at m and m perpendicular distance from line charge towards sheet charge, respectively. '' and '' are the magnitudes of resultant electric field intensities at point 'P' and 'Q', respectively. If for , then the value of a is
