Answer:
D) 30°
Explanation:
This is in accordance to the Gauss Law which states that, <em>the electric flux through any closed surface is equal to the total charge enclosed by the surface divided by the permittivity of free space.</em>
Mathematically given as:
where
θ = the angle between the electric field lines and area vector normal to the surface.
When the area vector has formed an angle of 60° then the plane is at 30° and we know <em>cos 60° = 0.5</em>
