Question

Define electrostatic intensity at a point due to a charged body . Find an expression for it ?​

Answer 1

Answer:

Electric field intensity is the strength of an electric field at any point. It is equal to the electric force per unit charge experienced by a test charge placed at that point, or E=qF. From Gauss law, considering a spherical surface with charge at its center as Gaussian surface, E(A)=ϵ0q. ⟹E(4πr2)=ϵ0q.

Electric field intensity is the strength of an electric field at any point. It is equal to the electric force per unit charge experienced by a test charge placed at that point, or E=qF. From Gauss law, considering a spherical surface with charge at its center as Gaussian surface, E(A)=ϵ0q. ⟹E(4πr2)=ϵ0q.
