Question

Two infinite plane parallel sheets separated by a distance ‘d’ have equal and opposite uniform charge densities σ. Electric field at point between the sheets is 

(i) Zero 

(ii) \(\frac{σ}{ɛ_o}\) 

(iii) \(\frac{σ}{2ɛ_o}\) 

(iv) Depends on the location of the point .

Answer 1

Correct option is : (ii)  \(\frac{σ}{ɛ_o}\)
E = E₁ - E₂ 

= \(\frac{σ}{2ɛ_o}\) - \((-\frac{σ}{2ɛo})=\frac{σ}{ɛo}\)
