Consider a positive charge q at O. Imagine a sphere of radius r with centre O as shown in the figure. The magnitude of electric field intensity at every point on the surface of the sphere is the same and is directed radially outwards. Let ds represent a small area element on the surface of the sphere. The direction of the area element vector will be along
. i.e. θ = 0°.
