Electrostatics question

2023 · 13 Apr · Shift 1 · Q70

JEE MainPhysicsElectrostaticsNumerical+4 / −1
A thin infinite sheet charge and an infinite line charge of respective charge densities +σ+\sigma+σ and +λ+\lambda+λ are placed parallel at 5 m5 \mathrm{~m}5 m distance from each other. Points 'P' and 'Q' are at 3π\frac{3}{\pi}π3​ m and 4π\frac{4}{\pi}π4​ m perpendicular distances from line charge towards sheet charge, respectively. 'EP\mathrm{E}_{\mathrm{P}}EP​' and 'EQ\mathrm{E}_{\mathrm{Q}}EQ​' are the magnitudes of resultant electric field intensities at point 'P' and 'Q', respectively. If EpE0=4a\frac{E_{p}}{E_{0}}=\frac{4}{a}E0​Ep​​=a4​ for 2∣σ∣=∣λ∣2|\sigma|=|\lambda|2∣σ∣=∣λ∣, then the value of aaa is ‾\underline{\hspace{2cm}}​.
