VITEEE 2015 Discussion Forum › Electricity and magnetism questions › work done

Two uniformly charged plane sheets S₁ and S₂ having charge densities âˆ‚₁ and âˆ‚₂ (âˆ‚₁ > âˆ‚₂) are placed at a distance 'd' apart, parallel to each other. A charge q₀ is moved along a line of length a (a < d) at cm angle 45⁰ with normal to S₁. Work done by the elctric field is???????????

a) (âˆ‚₂ - âˆ‚₁)a q₀ / 2âˆš2 E₀

B) (âˆ‚₂- âˆ‚₁)a q₀ / âˆš2 E₀

C) (âˆ‚₁ - âˆ‚₂)a q₀ / 2âˆš2 E₀

D) (âˆ‚₁ - âˆ‚₂) Q₀ / a E₀
