Chapter-1|Electric Charges and Fields | NCERT 12th Physics:
Electric Field Due to System of Charges:
Let we consider n point charges q₁, q₂, q₃,…… qₙ with position vector r₁, r₂, r₃……rₙ exert forces F₁, F₂, F₃,…..Fₙ on test charge q₀ placed at origin O.
If E is electric field at point P due to the system of charges, then by principle of superposition of electric fields.
