JEE Main 2024 Physics question

An infinite plane sheet of charge having uniform surface charge density +σ C/m is placed on x-y plane. Another infinitely long line charge having uniform linear charge density +λ C/m is placed at z = 4m plane and parallel to y-axis. If the magnitude value |σ| = 2|λ| then at point (0, 0, 2), the ratio of magnitudes of electric field values due to sheet charge to that of line charge is π : 1. The value of n is .
