Answer 2

Explanation:

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

⟹E=4πϵ0r2q

which is the intensity of electric field at a distance r from the charge.
