Q.

Three infinitely long charged thin sheets are placed as shown in figure. The magnitude of electric field at the point P is xσε0. The value of x is _____ (all quantities are measured in Sl units).              [2024]


Ans.

(2)       E=E1+E2+E3

            =σ2ε0(-i^)+-2σ2ε0(i^)+-σ2ε0(i^)

             =-4σ2ε0i^=2σε0(-i^)
