Three infinitely long charged thin sheets are placed as shown in figure. The magnitude of electric field at the point P is xσ/ε₀. The value of x i $s _________$ (all quantities are measured in SI units).

Question

G1 Physics · Accepted Answer

Image Electric field due to an infinite sheet has magnitude: E = |σ|/(2ε₀) At point P, adding the fields of the three sheets with their correct directions gives: E(P) = -(2σ/ε₀) î Therefore, magnitude is: 2σ/ε₀ Hence: x = 2
